Design and Realization of Gaussian White Noise with Limited Bandwidth

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.
