卷积码编码与Viterbi译码的MATLAB仿真研究(Convolutional coding and Viterbi decoding of the MATLAB simulation)

从多层树中取得偶数生成列，取得动态目标值的个数，从两个不同的树中，提取第二个树中独有的元素（和第一个树的元素不同的元素），并计算其和。(Generated columns to obtain an even number, the target value obtained from the dynamic multi-tree, from two different tree, extracts a second element that is unique in the tree (a tree of elements and different elements), and and calculate its.)

通过虚拟阵元进行DOA估计，基于chebyshev的水声信号分析，时间序列数据分析中的梅林变换工具。( Conducted through virtual array DOA estimation, Based chebyshev underwater acoustic signal analysis, Time series data analysis Mellin transform tool.)

一个单相逆变器，控制环路采用的是MATLAB里面的PID模块，有电流环和电压环，PWM发波模块采用的是MATLAB里面的PWM模块，省去了spwm的脉宽调制，需要在matlab2013中使用，较低版本没法运行(A single-phase inverter control loop uses PID module of MATLAB, current and voltage loop, a PWM wave module adopts the PWM module of MATLAB, eliminating the SPWM pulse width modulation and need to use in matlab2013, lower version did not run)
