View page
US Patent:
6359897, Mar 19, 2002
Filed:
Nov 3, 1998
Appl. No.:
09/184716
Inventors:
Clifford Hessel - Rochester NY
Michael E. Kreeger - Rochester NY
Christopher D. Mackey - Spencersport NY
John E. Gorton - Rochester NY
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H04L 1254
US Classification:
370429, 370428, 370464, 370466, 370474, 36523003, 36523005, 709213, 709215, 709245, 709250
Abstract:
A system and method for controlling the output of multi bit digital signals from a field configurable radio frequency communications system having a first register adapted to receive multi bit digital signals from a variety of sources, wherein the register includes a tag section for providing tag bits to the signal bit to identify the source of the signal. A second register is provided for using the tag bits for storing the multi bit signals according to the source of the signal. The multi bit signals and tag bits can be outputted directly from the first register, or from the second register, depending on the mode of operation selected by the output signal receiving circuit.

Field Programmable Modulator-Demodulator Arrangement For Radio Frequency Communications Equipment And Method Therefor

View page
US Patent:
6381265, Apr 30, 2002
Filed:
Nov 3, 1998
Appl. No.:
09/184711
Inventors:
Clifford Hessel - Rochester NY
Michael E. Kreeger - Rochester NY
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H04B 138
US Classification:
375219, 375269, 375271, 455 84
Abstract:
A digital signal processing circuit for field programmable radio frequency communications system including a digital controlled numerical controlled oscillator (NCO), dual digital signal conditioning circuits, and dual mixer circuits. The various circuits are responsive to digital commands for configuring the digital signal processing circuit to function with a variety of signaling schemes or waveforms. When configuring for angle modulation, a single conditioning and mixer is used and the modulating digital input signal is up converted to the center frequency of the NCO by the conditioning circuit and applied to an offset input of the NCO.

Assignee:
Harris Corporation - Melbourne FL
International Classification:
H04L 2700
US Classification:
375259, 375377, 710104, 710130, 713100
Abstract:
A system and method for providing a configurable signal processing circuit for a field configurable radio frequency communication system that is adaptable to be configured to function with a variety of signaling schemes or waveforms, and including an intermediate frequency (IF) digital signal processing circuit. A âtool boxâ of configurable signal processing circuits is available for processing multi-bit digital signals into and out of the IF circuit. Control registers receive digital instructions to select, interconnect and configure various circuits from the tool box to provide added signal processing for the selected the transmitter or receiver mode of operation as a function of the selected signaling scheme.

US Patent:
6590942, Jul 8, 2003
Filed:
Nov 3, 1998
Appl. No.:
09/184941
Inventors:
Clifford Hessel - Rochester NY
Paul E. Voglewede - Churchville NY
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H04L 2714
US Classification:
375326, 375316, 375344
Abstract:
A method and apparatus for estimating the frequency of a carrier signal associated with a modulated signal carrying digital data in which the signal is demodulated by a demodulator that includes a numerical controlled oscillator and a least squares fit regression analysis is performed on phase samples of the digital output of the demodulator to provide the slope of the phase, i. e. the frequency offset from the carrier signal. The frequency offset information may be used to adjust the numerical controlled oscillator.
