摘　　要：针对目前测试卫星通信传输链路误码率需要庞大和昂贵的硬件资源现状,我们借助于安捷伦公司的ADS软件仿真平台,通过和测试仪器无缝连接的半实物仿真技术,搭建了一条完整的卫星通信链路,并利用ADS软件中的"重点采样法"统计通信误码率。通过这种仿真和实验,证明该设计方法概念清晰,开发周期较短,降低了设备成本。According to the situation that considerable and expensive hardware was needed to test bit error rate （BER） of satellite communication link at present, a new method for communication BER test was established. Assisted by Agilent＇s ADS software simulation platform, a complete satellite communication link was built up through hardware-in-the-loop simulation system connected with testing instrument seamlessly. Thus communication BER could be calculated through ＂Improved Importance Sampling Technique＂ of ADS software. Those results show the concept of this method ias clear, development cycle is short and equipment cost is reduced.
