Method And Apparatus For Dynamically Adjusting A Transmitter's Impedance

View page
US Patent:
7379714, May 27, 2008
Filed:
Dec 27, 2004
Appl. No.:
11/022703
Inventors:
Tanbir Haque - Long Island City NY, US
Alpaslan Demir - Commack NY, US
Leonid Kazakevich - Plainview NY, US
Gerard Klahn - Sayville NY, US
Assignee:
InterDigital Technology Corporation - Wilmington DE
International Classification:
H04B 1/02
US Classification:
455107, 455123, 455125, 4551151, 375304, 375315, 343860, 343861
Abstract:
A method and apparatus for dynamically adjusting the impedance between a transmitter's power amplifier (PA) and antenna to efficiently transfer power from the PA to the antenna. The impedance between the PA and the antenna is adjusted based on power level measurements and/or PA direct current (DC) consumption measurements, depending on whether the PA is a linear PA or a switch-mode PA. In another embodiment, a hybrid PA including a first stage linear PA and a second stage switch-mode PA is implemented in a transmitter. The hybrid PA selectively connects the output of the first stage linear PA to one of the input of the second stage switch-mode PA and the output of the hybrid PA, depending on the output power level of the first stage linear PA, the output power level of the hybrid PA, or a requirement indicated by a transmit power control (TPC) command.

Method And System For Implementing Smart Antennas And Diversity Techniques

View page
US Patent:
7660561, Feb 9, 2010
Filed:
Jan 22, 2004
Appl. No.:
10/769690
Inventors:
Leonid Kazakevich - Plainview NY, US
Gerard Klahn - Sayville NY, US
Fatih Ozluturk - Port Washington NY, US
Assignee:
InterDigital Technology Corporation - Wilmington DE
International Classification:
H03C 7/02
US Classification:
455101, 465 6711, 465522, 465510, 375150, 375347
Abstract:
Method and apparatus for transfer of signals from multiple antennas down to baseband over a common radio frequency (RF) chain. Antenna selection having greater flexibility and applicability to both uplink and downlink is obtained by giving priority to the antenna receiving a better/best quality signal. Measurements are taken by at least a channel estimator during each time slot to determine the weighting to be given to the antenna with the better/best quality signal. Techniques and apparatus are provided to take measurements over a range of intervals from time slots to single symbols, for example, to select the best signal. The techniques described herein may be used individually, and in some cases are combined to receive additional benefits in efficiency. For example, one or more of recent and/or current channel estimation, history, optimization may be employed, in addition to channel estimation, to determine signal quality.

Apparatus For Reducing Channel Interference Between Proximate Wireless Communication Units

View page
US Patent:
20050226345, Oct 13, 2005
Filed:
Mar 21, 2005
Appl. No.:
11/085695
Inventors:
Gerard Klahn - Sayville NY, US
Robert Troiano - Farmingdale NY, US
Fryderyk Tyra - Huntington Station NY, US
Timothy Axness - Collegeville PA, US
Assignee:
InterDigital Technology Corporation - Wilmington DE
International Classification:
H04B001/38
US Classification:
375295000
Abstract:
Apparatus for reducing adjacent channel interference between proximate wireless communication units. Each wireless communication unit includes a digital baseband circuit and an analog baseband circuit. The digital baseband circuit includes at least one group delay compensation equalizer and at least one finite-impulse response (FIR) filter. The analog baseband circuit includes a radio (transmitter section), a power amplifier and a narrowband filter. The narrowband filter compensates for deficiencies of the power amplifier including distortion and radio frequency (RF) power spill over. The group delay compensation filter compensates for undesired characteristics (e.g., group delay variation) exhibited by the narrowband filter.

Method And Apparatus For Adaptively Selecting Sampling Frequency For Analog-To-Digital Conversion

View page
US Patent:
20060045126, Mar 2, 2006
Filed:
Jun 27, 2005
Appl. No.:
11/167341
Inventors:
Gerard Klahn - Sayville NY, US
Fryderyk Tyra - Huntington Station NY, US
John Haim - Baldwin NY, US
Tanbir Haque - Long Island City NY, US
Assignee:
InterDigital Technology Corporation - Wilmington DE
International Classification:
H04J 3/16
US Classification:
370465000
Abstract:
The present invention is related to a method and apparatus for adaptively selecting local oscillator (LO) and sampling frequencies for analog-to-digital conversion of a plurality of input signals for transmitting two or more services via two or more frequency bands. Each input signal carries a different service via a different frequency band. Each service is subject to a minimum signal-to-interference, noise and distortion ratio (SINAD) requirement. The input signals are converted to an intermediate frequency (IF) band signals by mixing the input signals with LO signals. The LO and sampling frequencies are adjusted such that the converted IF band signals of the input signals are spectrally adjacent or overlapping each other to some degree. SINAD of the services is measured at each of a plurality of spectrally overlapping conditions. The LO frequencies and the sampling frequency are then adjusted based on the SINAD measurement results.

Method And Apparatus For Processing Multiple Wireless Communication Services

View page
US Patent:
20060046773, Mar 2, 2006
Filed:
Jun 20, 2005
Appl. No.:
11/156745
Inventors:
Erica Aycin - W. Babylon NY, US
Gerard Klahn - Sayville NY, US
Tanbir Haque - Long Island City NY, US
Assignee:
InterDigital Technology Corporation - Wilmington DE
International Classification:
H04B 7/08
H04M 1/00
US Classification:
455552100, 455140000
Abstract:
The present invention is related to a method and apparatus for processing multiple wireless communication services in a receiver. A receiver receives more than one wireless communication service simultaneously via a wireless interface. Each service is transmitted via a different carrier frequency band. The multiple received carrier signals are down-converted to an intermediate frequency (IF) band using a mixer and a local oscillator (LO). The LO frequencies are set such that the down-converted IF bands of the multiple services are fallen into a single IF band.
