Research Abstract

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.
