Abstract
A method and system that enables the usage of sounding-based feedback or analog feedback in a MIMO communication system with non-beamformed or broadcast pilot symbols is disclosed. The mobile station may employ a feedback channel to send a sounding waveform to a base station a feedforward channel to receive from the base station codebook weights derived from the send sounding waveform a receiver to receive communication from the base station and a processor to detect beamformed data from the received communication and received codebook weights from the base station. The base station processes the sounding waveform to determine codebook weights on groups of subcarriers. Additionally the base station transmits the beamformed payload and broadcast pilots to the mobile station.
