用蒙特卡罗仿真研究一个通信系统的误比特率BER。假设通信系统满足条件：信源输出的数据符号是相互独立和等概的；在发射机中没有进行脉冲形成；信道是AWGN信道(Using Monte Carlo simulation of a communication system bit error rate BER. Suppose communications systems to meet the conditions: the data source output symbols are independent, and so almost the no pulse in the transmitter in the form channel is AWGN channel)

用Matlab仿真实现最小二乘法和总体最小二乘法估计 假设仿真的观测数据 产生，其中 为0均值， 单位方差的高斯白噪声，取n=1,2,....128。 试用TLS，取AR阶数为4，估计AR参数 和正弦波频率；再用SVD-TLS ，估计AR参数 和正弦波频率。 (1)、在仿真中，AR阶数取为4和6。 (2)、执行SVD-TCS时，AR未知。仿真运行至少二十次。 (Simulation using Matlab and the overall least squares least squares estimate assumptions simulated observation data are generated, where 0 mean, unit variance Gaussian white noise, take n = 1,2 ,.... 128. Try TLS, take AR order of 4, estimated AR parameters and the sine wave frequency then SVD-TLS, estimated AR parameters and the sine wave frequency. (1), in the simulation, AR order is taken as 4 and 6. (2), when the implementation of SVD-TCS, AR is unknown. Simulation run at least twenty times.)
