Abstract:
1. A method for recovering data transmitted in a wireless communication system, wherein the wireless communication system comprises a plurality of receive antennas, comprising: receiving at least one data stream, wherein each data stream comprises a plurality of modulation symbols for a plurality of transmitted coded bits; wherein the plurality of modulation symbols for each receive antenna is a respective modulation or coding scheme; determining for each data stream a plurality of soft decision symbols based on the received plurality of modulation symbols and a first a priori information for the transmitted coded bits; determining a second a priori information based on the plurality of soft decision symbols and the first a priori information for the transmitted coded bits; determining the first a priori information for the transmitted coded bits based in part on the second a priori information; repeating the determining the plurality of soft decision symbols and the determining the first a priori information and a plurality of times; determining decoded bits for the transmitted coded bits based on the second a priori information.
