Abstract

The combination of Space Time (ST) coding and Continuous-Phase Modulation (CPM) produces a low power, energy efficient communication scheme suitable for wireless transmission. Space-time coding increases the reliability of transmission, and continuous-phase modulation (CPM) has the potential to provide considerable energy savings. In this paper, we show the performance of STBC-OFDM-CPM with different modulation indices and different subcarriers for Gaussian channels and Rayleigh fading environment.
