Wireless Communications System Having A Space-Time Architecture Employing Multi-Element Antennas At Both The Transmitter And Receiver

View page

US Patent:

6763073, Jul 13, 2004

Filed:

Jun 15, 2001

Appl. No.:

09/882120

Inventors:

Gerard Joseph Foschini - Sayreville NJ
Glenn David Golden - Boulder CO

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04L 2728

US Classification:

375260, 455 69

Abstract:

The bit rate at which a digital wireless communications system communicates data in scattering environments may be significantly increased by using multiple antennas at both the transmitter and receiver and by decomposing the channel into m subchannels. In the same frequency band, m one dimensional signals are transmitted into a scattering environment which makes these transmitted signals appear spatially independent at the receiver antenna array. The high bit rate is enabled by special receiver processing to maximize the minimum signal-to-noise ratio of the receiver detection process.

Method Of Coordinated Wireless Downlink Transmission

View page

US Patent:

7983710, Jul 19, 2011

Filed:

May 31, 2007

Appl. No.:

11/809354

Inventors:

Gerard J. Foschini - South Amboy NJ, US

Assignee:

Alcatel-Lucent USA Inc. - Murray Hill NJ

International Classification:

H04B 7/00

US Classification:

455524, 4554221, 455403, 455517

Abstract:

To reduce intercell interference, a method of coherently coordinated downlink transmission in a wireless network involves coordinating transmissions from a plurality of base stations to a plurality of wireless units, for coherent, reinforced reception of the transmitted signals at the wireless units. Thus, transmissions from the base stations are coordinated such that signals received at each wireless unit's particular location constructively add, but cancel out at other locations. The signals are generated based on a zero-forcing operation, e. g. , by applying zero-forcing complex antenna weight vectors to data symbols designated for transmission to the wireless units. For fairness, the signals are transmitted at no less than a guaranteed common rate. A convex optimization problem (which incorporates a per-base station power constraint or a per-transmission antenna power constraint) is solved to maximize the guaranteed common rate. Dirty paper coding may also be employed.

Open-Loop Diversity Technique For Systems Employing Four Transmitter Antennas

View page

US Patent:

20020118770, Aug 29, 2002

Filed:

Dec 29, 2000

Appl. No.:

09/752637

Inventors:

Gerard Foschini - Sayreville NJ, US
Constantinos Papadias - Westfield NJ, US

International Classification:

H04L001/02

US Classification:

375/267000

Abstract:

When using four transmit antennas, conventional channel coding is employed for a decoupled space-time coding approach for each of a number, L, of data substreams derived from the overall source bit stream. The symbols of the data substreams, after any encoding, are processed and the resulting derivatives of the encoded data substreams, which includes at least the complex conjugate of one of the encoded symbols, are grouped to form four transmit time sequences each one spanning L symbol periods which form a transmission matrix B. Each row of the matrix corresponds to an antenna, and the elements of each row represent the samples of a temporal sequence that is emitted by the antenna in L symbol periods. When L=4 the matrix B can be arranged as follows: where b, b, b, and bare the encoded symbols from the data substreams and * indicates complex conjugate.

Method Of Grouping Users To Reduce Interference In Mimo-Based Wireless Network

US Patent:

20080268834, Oct 30, 2008

Filed:

Apr 27, 2007

Appl. No.:

11/796328

Inventors:

Gerard J. Foschini - South Amboy NJ, US
Taesang Yoo - San Diego CA, US

International Classification:

H04Q 7/20

US Classification:

4554261

Abstract:

In a system of MIMO communications in a wireless network, a number of wireless units are logically divided into a plurality of user groups, through operation of a semi-orthogonal user selection sub-system. For example, the user selection sub-system may implement a heuristic user selection algorithm based on near-orthogonality. Each user group is assigned a discrete transmission channel, which may be orthogonally defined in terms of frequency, time, or code. Data is transmitted over the channels (e.g., from network base stations) in a coherently coordinated manner, according to a zero-forcing beamforming operation. The system may be configured for operation in a time/frequency selective manner, e.g., over time/frequency selective fading channels. The wireless units may be allocated to the time/frequency slots based on prioritization of channel strength and considerations of fairness, in conjunction with the application of a semi-orthogonal user selection algorithm.

Communication System And Method With Signal Constellation

US Patent:

20100150577, Jun 17, 2010

Filed:

Dec 16, 2009

Appl. No.:

12/639750

Inventors:

Gerard J. Foschini - Sayreville NJ, US
Gerhard Guenter Theodor Kramer - Chatham NJ, US
Peter J. Winzer - Aberdeen NJ, US

International Classification:

H04L 27/20
H04B 10/04

US Classification:

398188, 375308

Abstract:

An example method includes modulating an optical signal using a Phase Shift Keying (PSK) signal constellation, wherein signal points of the PSK signal constellation are located on at least two rings. The first ring has a first radius r and a second ring has a second radius r, wherein the first radius and second radius differ, and wherein the signal points are not located on a regular n-dimension lattice, where n is an integer. The regular n-dimension lattice is formed from a minimum number of lines parallel to an axis for each of the n-dimensions that connect ones of the signal points of the PSK signal constellation on either side of an origin of the axis. The second radius may be greater than the first radius, with the second radius a non-integer multiple of the first ring radius.

Interference Coordination For Communication Network

US Patent:

20120184203, Jul 19, 2012

Filed:

Jan 19, 2011

Appl. No.:

13/009330

Inventors:

Antonia M. Tulino - Lincroft NJ, US
Gerard J. Foschini - South Amboy NJ, US
Reinaldo A. Valenzuela - Holmdel NJ, US

International Classification:

H04B 15/00
H04B 7/14

US Classification:

455 7, 455501

Abstract:

Techniques are disclosed for interference coordination in communication networks. For example, a method comprises the following steps. Input information is obtained from a communication network. The input information comprises existing power levels associated with transmitting nodes in the communication network, and existing channel information associated with receiving nodes in the communication network. A coordinated resource set of future transmitting times and future power levels associated with the transmitting nodes and future decoding times associated with the receiving nodes that reduce interference in the communication network is determined. The coordinated resource set determination comprises evaluating a cost function for a given range of interference values based on at least a portion of the input information. In a downlink scenario, the transmitting nodes may comprise base stations and relays, and the receiving nodes may comprise user equipment. The method may also be applied to an uplink scenario.

Dynamic Spatial-Mode Allocation In An Under-Addressed Optical Mimo System

View page

US Patent:

20120224861, Sep 6, 2012

Filed:

Dec 21, 2011

Appl. No.:

13/332588

Inventors:

Peter J. Winzer - Aberdeen NJ, US
Gerard J. Foschini - Sayreville NJ, US

Assignee:

ALCATEL-LUCENT USA INC. - Murray Hill NJ

International Classification:

H04B 10/12

US Classification:

398143, 398141

Abstract:

The outage probability in an under-addressed optical MIMO system may be reduced by configuring a spatial-mode coupler at a transmitter and/or a spatial-mode separator at a receiver to dynamically change its spatial-mode configuration on a time scale that is shorter than the channel coherence time. Provided that the MIMO system employs an FEC code that has a sufficient error-correcting capacity for correcting the amount of errors corresponding to an average state of the MIMO channel established between the transmitter and receiver, this relatively fast dynamic change tends to reduce the frequency of events during which the number of errors per FEC-encoded block of data exceeds the error-correcting capacity of the FEC code.

Multipath Channel For Optical Subcarrier Modulation

View page

US Patent:

20120224863, Sep 6, 2012

Filed:

Jul 14, 2011

Appl. No.:

13/182513

Inventors:

Peter J. Winzer - Aberdeen NJ, US
Gerard J. Foschini - Sayreville NJ, US

Assignee:

ALCATEL-LUCENT USA INC. - Murray Hill NJ

International Classification:

H04B 10/00

US Classification:

398158, 398140

Abstract:

In a representative embodiment, a multipath channel and an optical subcarrier modulation scheme are designed in concert to cause different modulated subcarriers of the optical communication signal to become substantially uncorrelated over the aggregate signal bandwidth. Provided that the employed FEC code has sufficient error-correcting capability for average channel conditions, breakdowns in the operation of the FEC decoder and the corresponding system outages can substantially be avoided.
