Abstract: Despite the severe propagation conditions in shallow water acoustic telemetry channels, coherent high-speed data transmission may be established using adaptive receivers based on a decision feedback equalizer (DFE) structure. The performance of a DFE in shallow water acoustic networks is affected by substantial cochannel interference from acoustic modems, in addition to extended, time-varying ISI and large Doppler fluctuations. In this paper we address the interference suppression ability of a DFE by evaluating a channel-specific structure for reliable interference suppression and dynamic channel tracking. The DFE performance is compared to adaptive multiuser receiver which jointly performs adaptive equalization and multiple-access interference cancellation.
