METHOD AND APPARATUS FOR MULTIPLE ACCESS IN A WIRELESS COMMUNICATION SYSTEM

摘要

An access node for use in a wireless communication system that includes a controller configured to coordinate transmission of a plurality of symbol sequences in a coherence interval by transmitting information to a plurality of transmitters. The transmitted information includes a number of time slots in the coherence interval after which the transmitter shall begin transmitting its symbol sequence. A receiver receives the symbol sequences with a plurality of antennas and a decoder decodes the plurality of symbol sequences based on the coordination of the transmission of the plurality of symbol sequences. The decoder is configured to detect a pilot symbol of a second symbol sequence based on a superposition of the pilot symbol with a data symbol of a first symbol sequence and based on an estimation of the data symbol.
