Combining Signals Exhibiting Multiple Types Of Diversity
US Patent:
6833810, Dec 21, 2004
Filed:
Jan 17, 2003
Appl. No.:
10/346906
Inventors:
George P. Bortnyk - Seminole FL
David J. Lupia - Oldsmar FL
David J. Lupia - Oldsmar FL
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01S 7285
US Classification:
342189, 342194, 342195
Abstract:
Combining signals includes receiving first signals having a first frequency and second signals having a second frequency. A first weight reflecting a signal-to-noise ratio associated with a first signal is determined for each first signal, and a first signal output is generate from the first signals in accordance with the first weights. A second weight reflecting a signal-to-noise ratio associated with a second signal is determined for each second signal, and a second signal output is generate from the second signals in accordance with the second weights. The first signal output and the second signal output are combined to yield a combined signal output.
Combining Signal Images In Accordance With Signal-To-Noise Ratios
US Patent:
6801867, Oct 5, 2004
Filed:
Aug 15, 2002
Appl. No.:
10/219128
Inventors:
George P. Bortnyk - Seminole FL
Assignee:
Raytheon Company - Waltham MA
International Classification:
G01R 3500
US Classification:
702107, 382100, 348614
Abstract:
Combining signal images includes receiving signal images and performing the following to yield a weighted sum for at least one signal image. A phasor is generated from a signal image in accordance with a correlation reference, and a phase alignment of the signal image is adjusted to yield an adjusted signal image. A signal magnitude estimate is determined in accordance with the phasor, and a weight is determined in accordance with the signal magnitude estimate, where the weight reflects a signal-to-noise ratio of the signal image. The weight is applied to the adjusted signal image to yield a weighted sum for the signal image. The weighted sums are combined to yield a combined signal output.
Method And Apparatus For Baseband Tracking Of A Pn Code Sequence In A Spread Spectrum Receiver
US Patent:
4530103, Jul 16, 1985
Filed:
Aug 22, 1983
Appl. No.:
6/525297
Inventors:
William H. Mosley - St. Petersburg FL

Assignee:
E-Systems, Inc. - Dallas TX
International Classification:
H04K 104
US Classification:
375 1
Abstract:
A method and apparatus for baseband synchronizing of a local PN code sequence with a received PN code sequence incorporated in a received spread spectrum signal is provided. The received spread spectrum signal is translated to baseband to produce an I (in-phase) channel baseband signal and a Q (quadrature-phase) channel baseband signal. Data and error baseband correlators correlate the I channel and Q channel baseband signals with in-phase and quadrature-phase PN signals incorporating the local PN code sequence to produce despread on-time, advanced and delayed I channel and Q channel baseband signals. These despread baseband signals are processed and combined to produce an error signal proportional to a difference between the local PN code sequence and the received PN code sequence. A numerically-controlled oscillator circuit is responsive to the error signal to advance or delay the phase of a reference PN clock signal used to form a local PN clock signal. In operation, the rate of reading the local PN code sequence is accelerated or retarded to synchronize the local and the received PN code sequences.
