The dynamic MIMO detection that performs channel estimation and inverse matrix calculation of MIMO channels in every packet for the large time variation of channels and reuses the inverse matrix calculated in the last packet for the small time variation of channels under multipath fading channels has been realized. The dynamic MIMO detector has been designed by application specific instruction processor (ASIP) with vector operation and CORDIC and reduced its power consumption by the variable control of clock frequency and operating voltage.

实现了多径衰落信道下，对于信道时变较大的情况，对每个数据包中的MIMO信道进行信道估计和逆矩阵计算，对于时变较小的信道，重用最后一个数据包计算的逆矩阵的动态MIMO检测。动态MIMO检测器由具有矢量运算和CORDIC的专用指令处理器(ASIP)设计，并通过时钟频率和工作电压的可变控制来降低其功耗。
