DECODING OF SPACE-TIME CODED SIGNALS FOR WIRELESS COMMUNICATION

摘要

A method is disclosed for receiving and decoding space-time coded signals, received over a plurality of antennas. Also disclosed is a generalized approach for maximum likelihood decoding where a decision rule is formed for all of the transmitting antennas of a transmitter, and a decision is mad e in favor of the transmitted symbols that minimize the equation where, (r~) is t he signal received at time interval t, at receiving antenna j, h* .epsilon. t(i )j is the complex conjugate of the channel transfer function between the transmitter antenna that is transmitting symbol c i and receiving antenna j, and .delta. r(i) is the sign of symbol c i in the time interval t.
