摘要
在水声通信中,由于多径效应引起的时间延迟扩展不仅限制了信道的带宽,还引发了码间干扰(ISI),限制了系统的传输性能.为了降低码间干扰提升系统的传输性能,可采用自适应均衡器来限制码间干扰.采用基于LMS(LeastMean Square)算法的自适应均衡器来提升系统的传输性能,并通过Matlab进行仿真.
In the channel of the underwater acoustic, due to the muhipath caused time delay spread. The mul- tipath time delay spread not only limit the channel frequency band, but also leading to Inter-symbol Interference （ISI）, constraint the transmission performance of system. In order to reduce the ISI and increase the transmis- sion performance of system can use the adaptive equalizer to reduce ISI. In this paper, we will adopt adaptive e- qualizer that based on LMS （Least Mean Square） algorithm to improve the transmission performance of system through MATLAB simulation.
