N2 - Underwater acoustic channel is assumed to be one of the most challenging communication channels because of its variable multipath effect. To reduce the receiver complexity, we proposed a second order cone optimized underwater acoustic channel frequency domain equalization (SOC-UAFDE), which adjust the equalization coefficients by minimum the mean square error of the frequency domain equalization algorithm through second order cone programming. Meanwhile, to avoid the high peak to average power ratio in orthogonal frequency division multiplexing(OFDM) communication, single carrier block transmission based on pseudo noise(PN) extension is adopted, which shows great advantage in synchronization and channel estimation. Simulation result shows that the proposed algorithm speeds up the convergence and reduces the bit error ratio(BER) effectively.
