AOA algorothm in smart antennas

自适应学习字典代码：训练字典的MATLAB仿真程序，能够很好的认识字典训练事例 (Adaptive learning dictionary code: dictionary MATLAB simulation training, can very good dictionary training examples )

详细的卷积编码与维特比译码算法。产生随机信号，对信号进行卷积编码，然后经过数值转换、格雷编码，QPSK调制，进入加噪信道，之后进行QPSK解调，格雷解码， 数制转换、 维特比译码得到接收端的信号。(Detailed convolutional coding and Viterbi decoding algorithm. Random signal, the signal convolution coding, and then through numeric conversion, Gray coding, QPSK modulation, plus noise into the channel, followed by QPSK demodulation, decoding Gray, number system conversion, Viterbi decoding to get the receiving end of the signal.)

采用的是脉冲对消法，计算多重分形非趋势波动分析，利用matlab GUI实现的串口编程例子。( It uses a pulse of consumer law, Calculate the multifractal trend fluctuation analysis, Use serial programming examples matlab GUI implementation.)
