The high frequency Chirp signal in underwater acoustic communication usually submerged in various noise produced by ocean waves, ships, etc. In this paper, based on the principle of stochastic resonance for weak signal detection, the extraction and energy enhancement of high frequency weak signal are achieved by using bistable stochastic resonance system. The genetic algorithm is additionally used...
Underwater acoustic (UWA) channel was one of the most complex wireless communication channel because of extensive multipath problem. Multipath problem will lead to severe inter-symbol interference (ISI) and frequency selective fading. To build a reliable high rate UWA communication system in multipath environment, Sweep-Spread Carrier (SSC) system based on Virtual Time Reversal Mirror (VTRM) was introduced...
