logistic映射从倍周期分岔进入混沌的分岔图算法(Logistic mapping the period-doubling bifurcation into the bifurcation diagram of chaos algorithm)

这个是总结了各方面关于噪声的理解，主要是基于matlab计算信号时适用。(This is a summary of the understanding of all aspects of noise, mainly based on the calculated signal matlab apply.)

gold序列用于跳频通信，给出了gold序列生成跳频序列的生成函数，并给出高斯白噪声和多用户干扰下的误码率曲线。(gold sequence for frequency hopping communications, give the gold sequence generated hopping sequence generation function, and to give white Gaussian noise and multi-user interference of the bit error rate curve.)

说明：  ofdm程序，可以计算BER误码率，适合于入门(OFDM procedures, can calculate the BER bit error rate, suitable for entry-)
