encoding and decoding using huffnam

this code is used to plot the ECG signal data base from MIT-BIH,(physionet).

Shows the frequency spectrum and shows all occuring doh notes in the time domain.

梯度下降法在二维函数中的优化寻优，老师上课的例子，可以运行无误(Gradient descent optimization in a two-dimensional function optimization, teacher in the class example, you can run correctly)

通过matlab仿真分析了QAM 调制方式在AWGN信道下的误比特性能(By matlab simulation analysis of QAM modulation in AWGN channel BER performance)

说明：  多种波束形成源代码，有很好的可扩展性 包括：直接相移波束形成，MVDR波束形成，music波束形成的源程序(A variety of beamforming source code, has good scalability, including: direct phase-shifting beamforming, MVDR beamforming, music beamforming source program)

说明：  总体最小二乘法的ESPRIT方法，这种算法的估计精度明显好于原来的ESPRIT算法。可以很好的估计出信号的角度。仿真中用的是均匀阵列。(Total least squares method of the ESPRIT method, the algorithm of the estimation accuracy significantly better than the original ESPRIT algorithm. Can be a very good signal to estimate the angle. Simulation using the uniform array.)
