Maximum likelihood sequence estimation for multipath fading channels
This thesis addresses receiver design for multipath fading channels. The channel model was chosen to closely resemble a typical land mobile fading channel. Three receivers will be compared in this work. The first will be the optimum receiver in the maximum-likelihood (ML) sense. The optimum receiver represents the best possible bit error rate achievable. The second receiver will be based on the Expectation-Maximization (EM) algorithm. The EM algorithm is a recursive ML technique that can achieve close to optimal results with reduced complexity. The final receiver considered is the RAKE receiver. The RAKE receiver is a popular receiver structure that is currently being used for multipath fading channels. Simulation results are provided to compare the optimum and EM receivers and the RAKE and EM receivers. Simulations are also used to determine the performance of the EM receiver using different packet lengths and packet structures.
