On multilevel coded MPSK for the Rayleigh fading channel [PDF]
Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 1999 We derive a new upper bound on the pairwise error probability for MPSK sequences over the Rayleigh fading channel when channel state information (CSI) is not available. This is obtained by adding weight factors in calculating the symbol metrics. Simulation shows that the weight factors which optimize the upper bound are likely to optimize the error ...
