| Abstract: | The current paper addresses the issue of estimating the users propagation delays, received carrier phase offsets and received amplitudes in an asynchronous DS-CDMA environment with frequency non-selective propagation channels. The proposed synchronizer is based on the expectation- maximization (EM) algorithm and takes benefit from the soft information delivered by the receiver which is of turbo type. Performance of the proposed synchronizer is illustrated by simulation results. In particular, the mean and the mean squared error of the estimator as well as the bit error rate reached by the synchronized system are reported. | ||
