中文摘要：
论述了应用于水声信道的Turbo均衡技术，针对水声信道多径衰落引起的码间干扰（ISI），提出了一种改进的Max—Log-Map算法，该方法基于马克劳林级数展开公式改进了Max-Log—Map均衡算法递归因子的求解方法，提高了算法性能，并在给定的水声信道下进行了仿真与分析，仿真结果表明：改进均衡算法与Max-Log-Map算法相比，在误码率为10^-4时性能有近1dB的编码增益，与Log-Map均衡算法性能相近，有效地提高了水声通信可靠性。
英文摘要：
Turbo Equalization was discussed which was applied to underwater acoustic communication, and an improved Turbo equalization algorithm named Max-Log-Map was brought forward. A simulation based on a given underwater channel was made. The simulation results represent that performances are close to each other between improved TE-Max-Log-Map and Log-Map when BER is about 10^-4 and has 1 dB coding gain compared with Max-Log-Map. The improved Max-Log- Map method improves underwater acoustic eommunication＇s reliability.
