A system, terminal, receiver and method are provided for receiving and processing a signal received from a spread-spectrum downlink channel. The method includes receiving the signal from the downlink channel, and generating an estimate of a transmitted chip sequence in accordance with an iterative process. In this regard, the iterative process includes calculating statistical information, such as a mean and covariance, for a previous iteration of a transmitted chip sequence, the statistical information being selectively calculated based upon one of soft bits and soft symbols associated with the previous iteration of the transmitted chip sequence. The estimate for a current iteration of the chip sequence is then generated based upon the statistical information.
