Matrix operations are the most costly computational module within MIMO receivers but a matrix inversion algorithm is very easy to compute and significantly reduce the computational module cost. We will demonstrate the MIMO LTE applications for reducing the module cost by square matrix inversion ...
A modified version of the method for performing the inversion without explicitly generating the unit matrix by replicating its functionality within the original matrix space for more efficient utilization of computational resources is presented in this article. Although the algorithm described here picks ...
Matrix inversion is numerically sensitive and the NMSIS DSP library only supports matrix inversion of floating-point matrices. (a1,1a1,2a1,3|100a2,1a2,2a2,3|010a3,1a3,2a3,3|001)→(100|x1,1x2,1x3,1010|x1,2x2,2x3,2001|x1,3x2,3x3,3) Algorithm The Gauss-Jordan method is used to...
