Transmission 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 made in favor of the transmitted symbols that minimize the equation (10) where (9), (rt) is the 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 (ci) and receiving antenna j, and delta t(i) is the sign of symbol ci in the time interval t.
