摘要

Recently, single-carrier block transmission (SCBT) has been considered for phase-coherent underwater acoustic communication due to its reduced computational complexity and low peak-to-average power ratio. It offers a viable design alternative to the orthogonal frequency division multiplexing (OFDM) techniques. Spatial processing is considered for SCBT based high-rate underwater acoustic communication due to its ability to mitigate the channel fading and inter-symbol interference (ISI). A Multi-beam based frequency domain equalizer is proposed in this paper to improve the performance of communication system. Based on the real data collected from a lake test conducted in November 2011, the credibility of the proposed algorithm was identified. We find that the BER performance of beam diversity was slightly improved compared with the conventional element-domain multichannel equalizer. With BPSK modulation, at the range of 1.8km and data rate of 1500 bit/s, the multi-beam processing has no error bits.
