Abstract: An improved method is provided for identifying a repeated codeword in an incoming bit stream. The method includes: receiving an incoming bit stream having an expected codeword repeated a number of times; determining whether a group of incoming data bits correlates to the expected codeword, where each of the incoming data bits in the group need not match the corresponding data bit of the expected codeword; and determining whether the expected code word is repeated over a sequence of incoming data bits

Abstract: A method and system reduces data error in an automatic repeat request (ARQ) communications system. Data is code-combined in a communications session that uses an automatic repeat request protocol by sending alternate phases of an encoder state. The underlying signaling constellation is changed when code-combining performance degrades. An optimal signaling constellation and code rate can be determined from a previous packet acknowledgment (ACK) status or from a look-up table previously determined by use.

Abstract: Systems (200) and methods (100) for noise error amplitude reduction. The methods involve configuring a first microphone system (202) and a second microphone system (302) so that far field sound originating in a far field environment relative to the first and second microphone systems produces a difference in sound signal amplitude at the first and second microphone systems. The difference has a known range of values. The methods involve (128) dynamically identifying the far field sound based on the difference. The methods also involve (130, 132, 134) automatically reducing substantially to zero a gain applied to the far field sound responsive to the identifying step.

Abstract: A communications device includes a modulator and a filter downstream therefrom and operable to generate an output wideband complex signal with a frequency notch therein. The filter includes a finite impulse response (FIR) filter with L taps to generate N output values, with L>N. A Fast Fourier Transform (FFT) block is downstream from the FIR filter and has a length N so that filter transition regions occur between frequency bins of the FFT block. A notching block is downstream from the FFT block to generate the frequency notch. An Inverse Fast Fourier Transform (IFFT) block is downstream from the notching block and has the length N.
