摘要
对伪随机序列统计特性进行了分析,介绍了根据信噪比要求产生出方差可调的数字白噪声信号的依据和方法,并用插值法简化了运算过程,最后还介绍了用FPGA实现该发生器的简单过程和实例。
This paper analyzes the statistical characteristic of pseudorandom sequence, introduces the method of producing digital white noise signal with variable variance according to the requirement of signal_to_noise ratio and simplifies the calculating process by interpolation. Finally the white noise generator realized by using FPGA device is shown in brief.
