Asymptotical analysis and comparison of two coded modulation schemes using PSK signaling .II

For pt.I see ibid., vol.47, no.7, p.2782-92 (2001). In this paper we analyze a multilevel coded modulation system using phase-shift keying (PSK) signaling and transmitting over the additive white Gaussian noise (AWGN) channel. We reduce the analysis of the overall system to the analysis of each decoding level, considering them as a set of related channels. The concept of a "genie-aided communication system" is introduced to simplify the analysis. A comparison with the conventional coded modulation system, studied in part I of this work, and some results concerning the synthesis and analysis of practical multilevel modulation schemes concludes the paper.
