The receiver includes an estimator to estimate one or more channel taps. The estimator includes a memory to store at least a portion of one or more calculated values of an estimation matrix and is capable to estimate the one or more channel taps based on a stored portion of calculated values of the estimation matrix.

Abstract: A method of identifying a precoding matrix corresponding to a wireless network channel comprises the steps of identifying a capacity metric that includes an identity matrix, approximating the capacity metric using an approximation metric that ignores the identity matrix, using the approximation metric to search over all matrices in a matrix codebook in order to identify a particular precoding matrix that increases a capacity of the wireless network channel, and transmitting across the wireless network channel a matrix index that corresponds to the particular precoding matrix. Additional techniques for identifying precoding matrices are also described herein, as is a method of approximating a capacity of a wireless network channel in a wireless network.

Abstract: An embodiment of the present invention provides an apparatus that may include a transceiver operable to communicate with a receiver in a wireless network and adapted to select an optimal mode for transmissions, wherein the receiver estimates the optimal mode and feeds it back to the transceiver which changes a transmitted mode accordingly and wherein the optimal mode is based on a predetermined metric based on a performance equation that puts a threshold to separate between a high correlated signal to low correlation signal.

Abstract: In a structure having a fractional-N synthesizer driven by a voltage controlled oscillator, frequency accuracy is maintained by first using the fractional-N synthesizer to correct large frequency errors and then slowly transferring correction from the fractional-N synthesizer to the voltage controlled oscillator a little at a time.

Abstract: Methods, apparatuses, and systems to determine whether a transmission signal block was fully transmitted are described herein. The determination may be made at least in part by calculating one or more bit error probabilities for one or more to be transmitted bursts of the transmission signal block.

Abstract: System and methods for reducing false alarm in the presence of random signals are disclosed. Various embodiments are operable to receive via a data interface a data block having at least one frame, normalize soft bits of the data block and re-encode decoder output bits of the data block, calculate a normalized correlation metric from the normalized soft bits and re-encoded bits of the data block, compare the normalized correlation metric to a threshold, and reject the data block when the normalized correlation metric is below the threshold.
