Design and test of a multicarrier transmission system on the shallow water acoustic channel

On the shallow water acoustic channel, the transmission systems are exposed to some severe working constraints link to, on the one hand, the channel's non-stationarity and on the other hand, the presence of multiple paths. In order to solve these problems we suggest a multicarrier transmission system based on the OFDM principle which implementation by means of DFT is quite simple. The performance of such a transmission was evaluated from experiments carried out in the ocean and led to satisfying results.<
