Combined Array Processing to Suppress Interference for High Data Rate Wireless Communication.

Space-time block code (STBC) designs for two-user MIMO X channels are used to accomplish full diversity while the inter-user interference is cancelled by the group of zero-forcing receivers of channel codes for better data speed and consistency for wireless environment. The use of multiple transmitters and receivers as an alternative to single one can help out to recover consistency without any consequence in the bandwidth expenditure. This paper promotes the reduction in encoding and decoding complexity by partitioning antennas at the transmitter into tiny groups, by means of individual space?time codes, to transmit information from every cluster of antennas. By the side of the receiver, an individual space?time code is decoded by a new linear processing technique that suppresses signals transmitted by other groups of antennas by treating them as interference. An easy receiver structure is derived to provide diversity and coding gain above uncoded systems. This mixture of array processing at the receiver and coding techniques for multiple transmit antennas can provide trustworthy and incredibly elevated data rate communication over narrowband wireless channels. A modification of this fundamental structure gives rise to a multilayered space? time architecture which generalizes and improves upon the layered space?time architecture proposed by Foschini.
