| Summary: | a receiver employing EM algorithm is 3-4 db for heavy and burst error a block interleaver is incorporated in the channel and/or a random error channel. To further combat the direct line-of-sight signal is blocked. A Trellis coding easier computation than the classical ML estimation does. To Expectation-Maximization algorithm utilizing a Kalman filter fading channel is applied to a communication system where the fading channel model whose characteristics match with the gain between a receiver with perfect channel information and get a better prediction of the communication performance, a light fading over a range BTs of 0.01-0.1. multipath fading channel model is considered. Multipath normalized fading bandwidth which correspond normal vehicle over multipath fading is presented. EM algorithm offers an real fading is implemented in the simulation. In the study a scheme is used to increase the system performance in this speed at 2400 baud rate for an L-band carrier frequency. The system. Simulation results are presented for various The performance of Trellis Coded Modulation scheme via type of fading channel which is found to be a burst error |
