Patent ID: 8265177

Claim:
A method of generating a number of candidate beamforming vectors for transmission of high definition video data over a wireless medium, the method comprising: determining the number (N) of transmitter antennas; determining the number (Q) of candidate beamforming vectors to be constructed; providing a discrete Fourier transform (DFT) matrix comprising Q rows and Q columns; selecting N rows of the DFT; and generating an abridged matrix using the selected N rows, wherein each column of the abridged matrix is configured to be used as a candidate beamforming vector for transmission of a high definition video data signal, wherein the resulting candidate beamforming vectors are based on a phase between π and −π it for each phase information element, and the N rows of the DFT matrix are selected using a performance metric for measuring beam pattern correlation and such that any pair of candidate beamforming vectors are maximally separated.
