Abstract

This paper presents a simple approach for matrix inversion by using dichotomous coordinate descent (DCD) algorithm. The idea of the approach is that the DCD algorithm obtains separately the individual columns of the inverse of the matrix. Owing to the low complexity of hardware implementation of the individual DCD algorithm, a block of DCD processors can be adopted to obtain the columns of the inverse of the channel correlation matrix in parallel with reduced hardware occupation.
