Patent ID: 7907689

Claim:
A method of receiving a broadcast transmission in a wireless multi-antenna communication system, comprising: obtaining, via a plurality of receive antennas, received data symbols for at least one data symbol block spatially processed with a plurality of steering matrices prior to broadcast from a plurality of transmit antennas to a plurality of receiving entities; obtaining a channel estimate for an effective multiple-input multiple-output (MIMO) channel formed by the plurality of steering matrices and a MIMO channel between the plurality of transmit antennas and the plurality of receive antennas; performing receiver spatial processing on the received data symbols with the channel estimate to obtain data symbol estimates for the at least one data symbol block; deriving a plurality of channel response matrices for a plurality of transmission spans in which the at least one data symbol block is broadcast, each channel response matrix including one of the plurality of steering matrices; and obtaining, via the plurality of receive antennas, received pilot symbols for a pilot spatially processed with the plurality of steering matrices prior to broadcast from the plurality of transmit antennas to the plurality of receiving entities, and wherein the channel response matrix for each of the plurality of transmission spans is derived based on the received pilot symbols.
