摘要
本文论述了在远程水声通信系统中提高系统可靠性的Turbo编码方案,对Turbo编码方案在给定的水声信道以及联合调制模式下的性能进行了仿真,对影响纠错性能的因素进行了分析,并对水声信道条件下的误比特率上限进行了推导,说明Turbo编码方案对远程水声通信系统的可靠性有较大改善。
The article describes the Turbo code scheme for improving credibility of the longrange underwater acoustic communication system. It simulates the performance of Turbo code under given underwater channel and modulation method, and analyzes the factors that affect its performance as well. The upper bound of BER in underwater channel is deduced, which proves that the performance of long-range underwater acoustic communication system can be well improved under Turbo code scheme.
