Two different single-element synchronous downlink multiple access schemes, interleave division multiple access (IDMA) and code division multiple access (CDMA) in conjunction with channel estimation, are considered for underwater communications channels. The proposed hard/soft chip channel estimation and carrier phase tracking are jointly optimized based on the mean square error (MSE) criterion and adopted iteratively by the reconstructed multiple access interference (MAI) signal, which is… CONTINUE READING
