Abstract

Official abstract text for this publication.

An equalizer is applied to a signal to be transmitted via at least one multiple input, multiple output (MIMO) channel or received via at least one MIMO channel using a matrix equalizer computational device. Channel state information (CSI) is received, and the CSI is provided as an input to the matrix equalizer computational device when the matrix equalizer computational device is not needed for matrix equalization. One or more transmit beamsteering codewords are selected from a transmit beamsteering codebook based on output generated by the matrix equalizer computational device in response to the CSI input to the matrix equalizer computational device.

First claim

Opening claim text (preview).

What is claimed is: 1. A method, comprising: receiving channel state information (CSI); selecting for an input of a matrix equalizer computational device of a matrix equalizer either i) a signal to be equalized or ii) the CSI, including selecting the CSI at a time when matrix computation circuitry of the matrix equalizer computational device is not needed for matrix equalization; when the signal is selected for the input of the matrix equalizer computational device, providing…
