| 摘 要： | 多径传播是随参信道的最突出的特点，对信号起着极其重要的作用．多进制幅相联合调制（APK或QAM）是通信调制的一种重要方式，多径传播效应对QAM信号比特误码的影响是决定实际数字通信系统性能的重要因素．本文深入探讨了1024QAM信号通过多径信道后的性能与特点，并用SystemView对其波形和系统BER（比特误码率）等主要性能进行了仿真和分析．

| Abstract: | With most prominent feature of the fast fading and muhipath transmission, random parameters channel plays a vital role in the right signals in itself. Amplitude Phase Keying （ APK or QAM） is a major way of communication modulations, the effects of BER to QAM signal from muhipath transmission is an important factor to determine the actual impact of digital communication system. Therefore, the importance is focued on studying in depth the Bit Errorcode Rate performance and haracteristics of 1024QAM signal through muhipath channel, and simulating and analysing of waveform and BER（ Bit Errorcode Rate） with SystemView. |
