Abstract
In this paper, we propose a variable tap-length multiuser detector (VT-MUD) for multiuser underwater acoustic communications. The proposed scheme adopts interleave-division multiple access (IDMA) and dynamically adjusts tap-length based on the accumulated squared error (ASE) to achieve a good balance between performance and complexity. Simulation results demonstrate that the proposed scheme can converge to the optimum tap-length and achieve better bit error rate (BER) performance than traditional fixed tap-length multiuser detector (FT-MUD).
