This paper addresses digital communication in a Rayleigh fading environment when the channel characteristic is unknown at the transmitter but is known (tracked) at the receiver. Inventing a codec architecture that can realize a significant portion of the great capacity promised by information theory is essential to a standout long-term position in highly competitive arenas like fixed and indoor wireless. Use (nT, nR) to express the number of antenna elements at the transmitter and receiver. An… 

Capacity When Using Diversity at Transmit and Receive Sites and the Rayleigh-faded Matrix Channel is Unknown at the Transmitter

The derivations hint at the existence of an architecture with extraordinary capacity that can be approached using one dimensional codecs as building blocks, termed the layered space-time architecture because of the way signals are stratified along diagonals in space- time.

Widely linear reception strategies for layered space-time wireless communications

It is shown that this detection strategy may be applied to wireless communication systems employing multiple transmit and receive antennas and adopting a noncircular modulation and that the improved receivers outperform the conventional ones both in terms of the error probability and of the capacity to cope with the power disparities that the fading channel may induce on the data streams transmitted by different antennas.

It is shown that when the channel has no ISI, then adaptive antennas, in the form of beamforming, can be combined with delay-diversity coding to achieve a diversity gain of mL and a large coding gain, whenever n/spl ges/L.
