Abstract :
In this paper, we demonstrate an exact analysis of bit probability for trellis coded modulation by using an analytical technique which is effective even in the region of low signal-to-noise power ratio (SNR). This employs an iterative calculation of probability density function (pdf) of path metric per transition, and is applicable for multilevel coded modulation. We show error performance results of 4-ary trellis coded modulation employing 2-state convolutional encoders
