Aiming at the main faults which influence high speed and high reliability of underwater acoustic communication, put forwards an improved RAKE receiver technology. Through research underwater acoustic communication channel decay features and underwater acoustic coherence multipath channel model, establish underwater acoustic spread spectrum model, analyze influence of coding technology on system performance in detail, then give simulation analysis and data of Rake receiver under different merger modes. The simulation results show that the method can solve the problem of multipath interference in underwater acoustic data transmission, it is effectively and feasibly.
