Abstract:
1. A method of transmitting data with a transmitting entity in a wireless multi-antenna communication system utilizing orthogonal frequency division multiplexing (OFDM), the method comprising: processing a data packet to obtain a block of data symbols at the transmitting entity; demultiplexing pilot symbols and the block of data symbols using OFDM onto a plurality of subbands to obtain, for the data packet, a plurality of sequences of pilot and data symbols for the plurality of subbands; and performing spatial processing, at the transmitting entity, on at least one of the pilot and data symbols for each subband with at least one steering vector selected for the subband, the spatial processing randomizing a plurality of effective single-input single-output (SISO) channels observed across the plurality of subbands.
