Abstract

Block coded modulation (BCM) is a bandwidth efficient scheme that results from the combination of block coding and modulation. The concept of BCM is applied to frequency/phase modulation (FPM) schemes, and the coding gain over uncoded M-PSK, BCM M-PSK, and TCM FPM systems is demonstrated. It is found that block code configurations of low complexity yield coding gains on the order of 3 dB over uncoded modulation while higher complexity codes further improve the performance. A procedure is described for the construction of BCM trellis diagrams, and examples that demonstrate the applicability of the procedure are included
