Abstract
A method of transmission in a wireless communication system having a transmitter and a receiver. In the transmitter: signals are encoded using a space-domain precoder for spatial multiplexing, time-domain variable delay is introduced at each signal communication path for time diversity, and the signal are transmitted to the receiver. In the receiver the signal transmissions from the transmitter are decoded using a space-domain decoder, wherein time diversity and spatial multiplexing are combined, to increase communication robustness and spectral efficiency.
