Abstract
The performance of a four-state trellis-coded differential eight-phase shift keying (8-DPSK) technique in fast Rayleigh fading characterizing realistic mobile radio channels is studied. A combination of one-bit and two-bit differential detectors is used at the receiving end. The Viterbi decoder is used to determine the most likely coded signal sequence directly from the unquantized channel outputs. The four-state trellis-coded modulation (TCM) schemes using 8-DPSK can improve the bit error rate.<>
