Abstract:
1. A transmitter comprising: a generator configured to generate a transmit signal stream; a transmit diversity encoder configured to receive the transmit signal stream and configured to generate a plurality, in number G, of transmit diversity/space-time encoded transmit streams from the transmit signal stream; a timing and synchronization module configured to generate a timing reference; a weight matrix generator configured to generate a plurality of weight vectors including at least one varying weight vector, wherein the weight matrix generator is configured to vary the at least one varying weight vector using the timing reference; and a plurality of beamforming encoders, each of the plurality of beamforming encoders configured to receive one of the plurality of transmit diversity/space-time encoded transmit streams and generate a plurality, in number K, of weighted substreams from the one of the plurality of transmit diversity/space-time encoded transmit streams by weighting the one of the plurality of transmit diversity/space-time encoded transmit streams by a corresponding weight vector of the plurality of weight vectors, wherein each weighted substream of the plurality of weighted substreams is configured to couple with a respective antenna of a plurality, in equal number K, of antennas independently of every other weighted substream in the plurality of weighted substreams.
