Error Performance Analysis for the Band-limited Optimum Digital Base-band System

本文针对带限信道最佳数字基带系统误码率公式应用中遇到的问题,以升余弦传输特性为例,推导了带限信道最佳数字基带接收机的误码率公式,明确了误码率公式中比特能量与带限系统参数的关系。笔者在SystemView仿真软件平台上构建了带限信道最佳数字基带系统,从而对其误码性能进行了仿真验证,证明了所推导结论的正确性。

For the applications of the BER of the optimum base-band system on band-limited channel, this article analysis the error performance for the optimum digital receiver of the band-limited base-band channel, therefore the relation between the bit energy and the parameters of the system is determined. Then the optimum digital base-band system of the band-limited channel is constructed and the error performance is simulated on the SystemView. The simulation shows that the analysis result is correct.
