Stratified Diagonal Layered Space-Time Architectures: Signal Processing and Information Theoretic Aspects

We consider an (M,N) wireless link, (M transmit antennas and N receive antennas), impaired by additive white Gaussian noise. The transmitter, which is subject to a power constraint does not know the outcome of the random matrix channel which has a static and flat frequency characterist It does know the channel statistics. The link operates at a limit on the probability of outage. We stratify diagonals in space-time to express a message for efficient communication with limited receiver complexity. The special message arrangement enables the receiver to substantially mute self interference caused by multipath, and, despite the M-dimensional transmit signal, avoid an explosion of processing complexity in the spatial domain.
