five Matlab Programs circular convolution

介绍实时系统的调度算法及控制实例，对实时系统学习者有很好的参考价值(Introduce real-time systems and control instances of scheduling algorithms for real-time systems have a good reference value for learners)

说明：  经典的Huffman编码，给定概率向量，输出相应Huffman编码(Classic Huffman encoding, given the probability vector, the output corresponding Huffman coding)

说明：  4. 试说明卷积编解码的工作原理。请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4 Explain the working principle of convolutional encoding and decoding. Please use the Simulink simulation convolutional coding and Viterbi decoding method used to decode, in which the encoding, decoding all write your own code (S-Function mode), instead of calling the Simulink existing encoding and decoding functions. In additive white Gaussian noise channel, signal to noise ratio and bit error rate to draw the curve.)

说明：  基于MATLAB的QPSK调制和解调，并包含对原理的解释和讲解(QPSK modulation and demodulation ,based on MATLAB)

说明：  基于谱减法的语音增强在MATLAB实现源程序(speech enhancement in MATLAB source)

说明：  云南降水于印太暖池热通量之间的CCA 典型相关程序(Yunnan Province in the Indo-Pacific warm pool precipitation heat flux canonical correlation between the CCA program)

MATLAB simulation of 50 cases of motor, the essence of synchronous motor in source code

本程序估计相干信号的DOA。当信源相干时，MUSIC不能处理，本程序利用了其他的DOA算法作为演示。(This procedure is estimated coherent signal DOA. When the source coherence time, MUSIC can not handle, use this program as a demonstration of other DOA algorithms.)
