摘要： A method and system for adaptive mitigation of noise interference in a receiver. In one embodiment of the invention, the receiver determines the type of the dominant noise interference among one or more noise interferences. The receiver determines or optimizes the estimation and averaging process of the noise covariance matrix based on the type of the dominant noise interference in one embodiment of the invention. This allows dynamic selection and adaptation of the noise estimate covariance matrix based on the noise type in one embodiment of the invention.

摘要： 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.
