Super-pseudo-orthogonal space-time trellis codes

In this paper, we propose super-pseudo-orthogonal space-time trellis codes. Compared with super-orthogonal space-time trellis codes, the proposed codes provide lower decoding complexity, lower peak-to-average power ratio and better performance. Furthermore, unlike super-quasi-orthogonal space-time trellis codes, it is easy to implement a differential modulation scheme based on the proposed codes when the channel state information is not available at the transmitter and the receiver. Simulation results demonstrate the good performance of our codes
