simulator pcm with noise using matlab

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.)

高斯消去法，用Matlab实现的。显然没有matlab自带的算法好，所以是练习以及和其他算法比较用的。(Gaussian elimination method, implemented with Matlab. Obviously there is no algorithm matlab own good, so is the practice and compare with other algorithms used.)

一个六杆机构的matlab仿真代码，包括其运动仿真，以及变量变化曲线图的生成。(A six institutions matlab simulation code, including its motion simulation, and variable changes in graph generation.)

将分布式检测器的概念和雷达联网的性能结 合在一起,从而可以得出在不同雷达布站和不同目标起伏条件下信号检测性能。此性能可以对 雷达布站方法和比较单、多站雷达性能研究都带来益处。 (In the paper, assume that the detection performance (such as detection probability and false alarm probability) in multistatic radars is given on condition:target movements, fluctuating tar- gets and different positions of the radars. )
