Abstract

This paper addresses the designing a high speed MIMO LTE receiver which is based on matrix inversion algorithm using floating point DSP. Matrix operations are the most costly computational module within MIMO receivers but matrix inversion algorithm is very easy to compute and significantly reduce the computational module cost. We will demonstrate MIMO LTE applications for reduce the MIMO receiver module cost by square matrix inversion algorithms.
