摘　　要：建立了“非线性变换”法的数学模型,对产生正态、瑞利、对数正态3种分布的随机数的自相关函数进行了分析计算。对m序列与存储器地址线非顺序连接的情形、地址线位数与量化噪声功率、截幅噪声功率及输出信号的自相关函数的关系进行了理论分析。由于此数学模型是建立在随机过程经非线性变换的理论上,所以它对用PRS作地址的这样一类“非线性变换”法方案都是适合的。This paper establishes a mathematical model of nonlinear transformation. Analysis and computer random number抯 self-correlation function of normality, rayl and lognormal. And gives an theory analysis of the bonded case between m-seriation and negate sequential connection of memory address line, order of units of address line and noise power of quantization, noise power of sever amplitude and self-correlation function of signal waveform. Because our mathematical mode is establish on the nonlinear transformation of stochastic process, it is very suitable to the kind nonlinear transformation such as address by PRS.
