摘要
高斯白噪声是卫星地面测试设备的一个重要功能模块,在一些调制信号源中通常需要加入高斯白噪声,用于星上接收设备的性能。该文提出了一种基于FPGA,功率和带宽均可调的高斯白噪声的设计方法,在均匀随机数的产生和工程设计方面都有了很大的改善,最大限度地减少了运算量,产生了比较理想的高斯白噪声,其使用方便灵活,并给出了相应高斯白噪声的实际性能。
Gaussian white noise is an important modulation of ground test equipment of satellite,for test the performance of the satellite re-ceiving equipment,some modelated signal source usually used by andding Gaussian white noise.This paper presents design the Gaussian white noise that power and bandwidth can be adjusted,based on FPGA.the uniform random number generation and engineering design have been greatly improved,producing the ideal Gaussian white noise,its easy and flexible to use,and list the the actual performance of the Gaussian white noise.
