Abstract :
This paper presents some new results on MMSE turbo equalization applied to real sea water trials in the Atlantic ocean. High data rate QPSK communications (2 to 7 kbps) have been tested. The receiver includes timing recovery, equalization, interleaving and channel coding. The results which are evaluated in term of BER and MSE show that turbo equalization improves the performance of the receiver.
