The error performance of a new family of super quasi-orthogonal space-time trellis codes (S-QSTTCs) for four transmit antennas on correlated MIMO channels is investigated. Two slightly different designs of S-QSTTCs, namely S-QSTTCs obtained by concatenating the extended Alamouti space-time code (EAC) with a simple outer trellis code and the concatenation of the ABBA code with a simple outer trellis code are compared in detail. It is shown that EAtype and ABBA-type S-QSTTCs perform quite
