用MATLAB仿真递推最小二乘法的新方法，但不是很完善，有待改进-Recursive least squares method using MATLAB simulation of the new method, but not perfect, room for improvement

MIMO系统递推最小二乘参数估计（本程序针对2入2出系统） 在实际通信系统仿真过程中非常有用-The multiple-input multiple-output (MIMO) system recursive least square parameters estimation (the program into a system for 2 2) In the actual communication system simulation process is very useful
