用贪心方法计算TSP路径，用的是matlab(TSP path with the greedy method, using matlab)

功率谱估计 信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为 和 ，初始相位 ，取 ， 取不同数值：0.3，0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Power spectrum estimation signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signal are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. Is the sampling frequency. Levinson recursive method were used and Burg method for power spectrum estimation, and change the length of the data analysis, the impact on the estimation model order spectrum.)

基于MATLAB的16QAM仿真设计，里面包括若干个M文件，使用者只要在MATLAB环境下运行，就能看到仿真结果。(MATLAB simulation of 16QAM based on the design, which includes a number of M documents, users simply run under MATLAB environment, you can see the simulation results.)

and this for chapter 4, chapter 3 just describe some theories.
