Application of Turbo Code in Underwater Acoustic Communication

摘要：

Long multi-path spreads and rapid time variations are the characteristic of underwater Acoustic channel. These characteristic limits the data rate of reliable communication systems, and require sophisticated equalization and coding technique, so Turbo coder/decoder is introduced. In this paper, a model including time-varying fading, multi-path and additive noise for underwater acoustic channel is built; some improved algorithms for turbo decoding are used in it. Simulation results show that: signal noise ratio at the range of that accepted by underwater acoustic communication, the performance of turbo is excellent. Then the sophisticated equalization is used with turbo coding technique together, the performance of communication is improved obviously.
