ABSTRACT The performance analysis of a system employing co-ordinate interleaving and constellation rotation, over Nakagami-m fading channels, in the presence of phase noise as well as additive white Gaussian noise, is presented. An upper bound for the average probability of bit error for M-ary phase shift keying is derived. It is shown that the derived upper bound is tight for high signal-to-noise ratios and in the presence of phase noise the optimum rotation angle does not change. Furthermore, it is shown that a system employing co-ordinate interleaving and constellation rotation is more robust against phase estimation errors.

Performance analysis of a system employing coordinate interleaving and constellation rotation in frequency-selective fading channels is presented. The achievable performance for L-branch microdiversity using maximum ratio combining (MRC) receiver is analyzed and an upper bound on the average probability of bit error (Pb) is presented. Exact closed form expressions for pairwise error probability (PEP) are derived for single-symbol transmission in

Rotation of the signal constellation together with in-phase and quadrature channel interleaving (signal space diversity) is known to provide good performance gains over fading channels for multi level modulation methods. This paper studies the extension of such schemes with a low density parity check (LDPC) code. It is shown that for both coded and un-coded Gray-mapped MPSK modulation formats with
