Abstract :
Two schemes for differential encoding of blockcoded M-ary PSK signals are presented and compared. Both proposed schemes perform differential encoding after channel decoding for minimizing the performance penalty associated with differential schemes. The first scheme requires the block codes to be rotationally invariant and linear, whereas the second requires rotational invariance only. Examples of bit error rate performance are also presented
