Asymptotical analysis and comparison of two coded modulation schemes usingPSK signaling - Part II

In this, the second part of the paper we analyze a multilevel coded modulat ion system using phase-shift keying (PSK) signaling and transmitting over t he 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 conve ntional coded modulation system, studied in Part I of this work, and some r esults concerning the synthesis and analysis of practical multilevel modula tion schemes concludes the paper.
