文件中为几类贝塞尔函数，基于MATLAB编写(Bessel functions of several files, based on MATLAB prepared)

1)football.m简单地以阵列形式显示一副图； 2）pre.m是心音信号过滤归一化预处理的过程； 3）wavlet.m是用db6小波进行信号的分解和重构，且求包络能量函数； 4）path.m是利用KKT条件的路径跟踪法，用于求解二次规划问题； 5）LRmmse是MIMO通信中常用检测方法，结合了最小均方误差准则和格基规约的知识。(1) football.m simply displays a graph in an array 2) pre.m is the process of normalized preprocessing of heart sound signal filtering 3) wavlet.m is a db6 wavelet for signal decomposition and reconstruction, and to find the envelope energy function 4) path.m is the path tracking method using KKT condition, which is used to solve the quadratic programming problem. 5) LRmmse is a commonly used detection method in MIMO communication, combining the knowledge of minimum mean square error criterion and lattice protocol.)
