Diversity can play an important role in the performance improvement of a communication system in fading channels. The achievable performance with signal space diversity (SSD) is analyzed and a closed form expression for the upper bound of average probability of bit error (Pb) for M-ary phase shift keying (MPSK) in Rayleigh fading channel is presented. The problem of calculating Pb of coherent MPSK over a Rayleigh fading channel has been studied previously in the literature. A solution based on the nearest neighbors was given. In this paper we show that the results with the nearest neighbor approximation represent an expurgated bound and are only valid for a small range of rotational angles. Exact pair-wise error probability (PEP) is derived for Rayleigh fading channels. It is shown that Gray signal constellation mapping is not necessarily the best option for a system employing coordinate interleaving and constellation rotation. Rotation angles are optimized by finding the minimum of the upper bound of Pb. It is shown that the new derived bound is tight for the entire range of rotational angles at high signal-to-noise ratio. Furthermore, the performance of the system in case of phase estimation error is also investigated by simulations. |
