Abstract: A method of transmitting a communication signal (FIG. 1) is disclosed. The method includes receiving a data signal (102). The method further includes receiving a codeword index (pre-coder selection) from a remote transceiver. A codeword is selected from a Householder matrix based codebook in response to the index. The data signal is precoded (104) in response to the selected codeword. The precoded data signal is transmitted (100) to the remote transceiver.

Abstract: A method and system is described for more optimally managing the usage of a wideband space-time multipath channel. The wideband space-time multipath channel is decomposed into a plurality of orthogonal sub-channels, where the orthogonal sub-channels having the best signaling characteristics are used for transmitting one or more signal streams. For purposes of decomposing the wideband space-time multipath channel into a plurality of orthogonal sub-channels, channel estimates are determined for each signal propagation path. A closed-form singular value decomposition of the channel corresponding to each receive antenna before coherent combining is utilized to obtain an orthogonal decomposition of the overall effective space-time channel after coherent combining. By using the overall effective space-time channel after coherent combining rather than before coherent combining, the complexity and correspondingly the resources required for obtaining the orthogonal sub-channels is significantly reduced.
