Non-Coherent Receiver Performance for Orthogonal Space-Time Coded CPM in Fading Channels

In mobile communication systems where bandwidth and power efficiency are at a premium, continuous phase modulation (CPM) is a viable modulation technique. In this paper, non-coherent receivers for orthogonal space-time coded continuous phase modulated signals transmitted over two antennas are derived using a maximum likelihood (ML) approach. The performance of these receivers is numerically characterized in Rayleigh fading channels
