Abstract :
A methodology for the design of M-PSK codes for the Rayleigh fading channel optimised for a specific target BER is proposed, using the framework of multilevel coded modulation. The principle is to equalise the BER at each stage of a multistage decoder. An 8-PSK code is designed which exceeds the performance of the code of Seshadri and Sundberg (1992) by 2.4 dB at BER=10-3 as well as 16-PSK codes optimised for BERs of 10-3 and 10-6. No additional interleaver delay is introduced beyond that required by the channel
