摘要
提出了一种基于FPGA的参数可调高斯白噪声发生器,给出了设计的总体方案、算法实现和设计要点。上位机可以通过通用异步收发接口进行实时参数配置和系统误码率统计。实测数据表明该方法可以满足实际通信系统的误码率测试。
This paper presents a Gaussian white noise generator with adjustable parameters based on field programmable gate array （FPGA）, gives the general system scheme, algorithm implementa- tion and some essential points of design. The upper computer can perform real time parameter con- figuration of the noise generator and bit error rate statistic of the system by means of universal a- synchronous receving/transmitting interface. The measured data practically demonstrate that the proposed method can meet the requirement of bit error rate testing of practical communication sys- tem.
