METHOD FOR SIGNAL TRANSMISSION-RECEPTION IN A MULTI-USER MULTIPLE TRANSMIT AND MULTIPLE RECEIVE ANTENNA RADIO COMMUNICATION SYSTEM

摘要

An apparatus and method for signal transmission-reception in a multi-user multiple transmit and multiple receive antenna radio communication system are provided. An aspect of the present invention is to enhance reception performance and increase the communication channel throughput. This is achieved by applying a new sequence of operations including a vector perturbation procedure along with an efficient perturbation vector searching technique based on single-dimensional optimization of a decision function. In addition, the method ensures simple implementation of a subscriber station receiver. The SS receiver is implemented as independent channels for processing signals of different receive antennas. The receiver can be implemented even if each subscriber station has only one receive antenna. Accordingly, the method proves highly efficient in virtually any propagation environment.
