摘      要：A novel criterion that is capac-ity rule and mapping rule for the design of op-timum MLC scheme over mobile fading channels *** to this theory,the performanceof multilevel coding with multistage decoding schemes(MLC/MSD) in mobile fading channels is investi-gated,in which BCH codes are chosen as componentcodes,and three mapping strategies with 8ASK mod-ulation are *** results indicate that whencode rates of component codes in MLC scheme are de-signed based on capacity rule ,the performance ofthe system with block partitioning (BP) is optimumfor Rayleigh fading channels,while the performance ofthe system with Ungerboeck partioning (UP) is bestfor AWGN channels.
