Abstract
A method of operating a communication system including at least two transmitting antennas and at least one receive antenna. Symbols are encoded across the at least two transmitting antennas during a coding interval. Data is received at each receive antenna and at each symbol of the coding interval. Channel gain estimates are provided between each transmitting antenna and each receive antenna at each symbol of the coding interval. An estimate of transmitted symbols is determined based on the channel gain estimates and the received data at each receive antenna at each symbol of the coding interval. An information unit is provided the estimates of the transmitted symbols to achieve spatial diversity in a communication link while mitigating channel variations.
