Abstract :
Super-orthogonal space-time trellis codes (SOSTTC) designed by hand can significantly improve the performance of space-time trellis codes. This paper introduces a new representation of SOSTTC based on a generator matrix that allows a systematic and exhaustive search of all possible codes. This verifies that some of the known codes are optimal, and provides a means to easily implement encoders and decoders with a large number of states without relying on a graphic representation.
