An Eigen-Based Approach for Enhancing Matrix Inversion Approximation in Massive MIMO Systems.
IEEE Transactions on Vehicular Technology(2017)
摘要
This correspondence presents a new matrix inversion approximation (MIA) method for massive multiple-input multiple-output systems (MIMO). In contrast to the existing methods that are mostly derived from the Neumann series expansion framework, additional coefficients have been introduced in our proposed method to enhance the precision of approximation. We propose an efficient algorithm for the coef...
