Abstract

A method for optimizing a bit-to-symbol mapping operation. The method has steps of (a) determining a most probable symbol selection error made during a space-time decoding operation; and (b) selecting a bits-to-symbol mapper such that a bit-to-symbol mapping step results in a most probable symbol selection error, made during a space-time decoding operation, causes a minimal number of bit errors. The bits-to-symbol mapping step can be carried out so as to minimize an average number of bit errors resulting from an occurrence of the most probable symbol selection error, as well as from an occurrence of at least a second most probable symbol selection error, during the space-time decoding operation. A space-time coded communications system that operates in accordance with the method is also disclosed.
