摘　　要：数字通信中必然会出现码间干扰,码间干扰的消除对提高能信系统的传输质量有重要意义.介绍了通信传输系统中自适应均衡器的组成及工作原理,并用MTLAB仿真软件对其效果进行分析.仿真结果表明,自适应均衡器能够有效地消除码间干扰,增强基带传输系统的传输特性.The ISI is bound to appear in digital communication, and the elimination of the ISI is very important to the improvement of communication quality. This paper introduces the constitution and working principle of the adaptable equalization in communication transmission systems, and analyzes its transmission effects with the simulation software MATLAB. The simulation results show that the ISI can be eliminated effectively with adaptable equalizers in baseband transmission, and the digital communication system takes on favorable transmission characters .
