Abstract :
This letter presents an exact analysis of bit error probability for trellis coded modulation with soft decision Viterbi decoding. It is shown that this analytical technique is effective for low signal-to-noise power ratio where bounds are useless. The extension to asymmetric constellation is also investigated.
