摘要： A method for efficient state transition matrix based LFSR computations are disclosed. A polynomial associated with a linear feedback shift register is defined. This polynomial is used to generate a single step state transition matrix. The single step state transition matrix is then modified into a more general k-step state transition matrix. The resultant combined matrix is reduced in size and can be multiplied by a state input vector, ultimately producing a plurality of next state-input vectors thereby providing improved efficiency in computing a LFSR.

摘要： In one embodiment, the present invention is a method for performing incremental preamble detection in a wireless communication network. The method processes non-overlapping chunks of incoming antenna data, where each chunk is smaller than the preamble length, to detect the signature of the transmitted preamble. For each chunk processed, chips of the chunk are correlated with possible signatures employed by the wireless network to update a set of correlation profiles, each profile comprising a plurality of profile values. Further, an intermediate detection is performed by comparing the updated profile values to an intermediate threshold that is also updated for each chunk. Upon receiving the final chunk, the correlation profiles are updated, and a final preamble detection is made by comparing the updated profile values to a final threshold. Detections are performed on an incremental basis to meet latency requirements of the wireless network.

摘要： A method and system for parallel computation of a linear sequential circuit (LSC) based on a state transition matrix is disclosed herein. A multistep state transition matrix and a multistep output generation matrix can be pre-computed and stored in association with the linear sequential circuit. The multiple state transitions and the multiple output bits can be computed by multiplying the current input-state vector with a multistep next state transition matrix and a multistep output generation matrix, respectively. Multiple state transitions and multiple output bits can be generated in parallel in a single clock cycle based on the pre-computed state transition matrix and the output generation matrix utilizing a dot product in order to improve computational speed. Such a simple augmentation provides a flexible and inexpensive solution for high speedup linear sequential circuit computation with respect to a processor.

摘要： A method of decoding interleaved Reed-Solomon codes to achieve an improved performance for burst errors is described. The method takes advantage of both interleaving and erasure decoding to increase the error correcting capability of a system without necessarily depending on channel reliability information. The observed correlation of burst errors in interleaved systems is advantageously used to achieve an improved error-correcting system, wherein a first code word is decoded, and the error locations in the first codeword are used to determine erasures for the remaining code words in the same interleaving block, and finally, decoding the remaining code words in parallel.

摘要： A receiver for a received signal having two or more different data levels comprises two or more channel estimators, (at least) one channel estimator for each different data level, where each channel estimator preferably implements an adaptive 2nd order or higher model of the transmission channel over which the received signals was transmitted to generate an estimated signal for one of the different data levels. The receiver also has a comparator that compares the current received signal to the estimated signals generated by the different channel estimators to select an output data value for the current received signal. The adaptive model of the transmission channel has coefficients that are dynamically controlled based on an error signal generated by the comparator. Each channel estimator relies on an output signal generated by an adaptive equalizer. In preferred shared-component implementations, each adaptive equalizer is shared by two or more different channel estimators, and, in one possible preferred shared-component implementation, all of the different channel estimators share a single adaptive equalizer.
