VHDL code for linear prediction filter based on RLS (recursive least square). Filter order is set to 4, bit precision set to 12 bits for input and output. Signals are complex signals.

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

本文从高速数字信号处理器的特点、自适应滤波器的原理及主要应用领域入手，介绍了自适应滤波器的基本理论思想，具体阐述了自适应滤波器的基本原理、算法及设计方法。本文中，对两种最基本的自适应算法，即最小均方误差(LMS)算法和递归最小二乘（RLS)算法进行了详细的介绍和分析，并针对两种算法的优缺点进行了详细的比较。最后用DSP实现了自适应滤波器。实验结果表明，该自适应滤波器滤波效果优越。(Starting from the characteristics of high-speed digital si
