The prior art teachings for encoding signals and transmitting them over a plurality of antennas are advanced by disclosing a method for encoding for any number of transmitting 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 the minimize the equation c i = arg min c R i - c 2 + ( - 1 + ∑ h i , j 2 ) c 2 n where R i = ∑ t = 1 n ∑ j = 1 m r t j h ɛ t ( i ) j * δ t ( i ) n r t j is the signal received at time interval t, at receiving antenna j, n h* ε 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 n δ t (i) is the sign of symbol c i in time interval t. |
