Abstract
Coherent underwater communication systems in shallow water must
compensate for several impairments, including Doppler shift and reverberant
channels.
In this paper, we quantify tradeoffs in communication performance vs.
computational complexity in designing receivers to compensate for these
impairments.
Our communication system is unidirectional, single-carrier, wideband,
and packet-based.
We use 1.5 hours of recorded data from an experimental system on a
public lake with a moving transmitter and stationary receiver.
Our contributions include tradeoff analysis for Doppler shift estimation,
multi-stage equalizers and sparse equalizers.
We compare multi-stage and sparse equalizers against traditional
equalizers.`
