使用正弦信号的相乘，然后取阈值，得到的伪随机信号，并且有频谱分析的结果(Sinusoidal signal is multiplied and then take the threshold to get pseudo-random signal and spectrum analysis of the results)

matlab入门书籍，对学习matlab有帮助(matlab entry books, learn matlab)

构建了简单的通信系统，其间对载波相位进行了估计，同时在函数中给出了估计误差，还计算了误码率以及采用信道编码的误码率(Construction of a simple communication system, during which the estimate of the carrier phase, and gives in function of the estimation error, also calculated BER and the channel coding error rate)

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。(constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.)

this is the most common type of fading model observing in urban cities
