Optimization of Linear Iterative Interference-Cancellation Receivers for CDMA Communications
N. Albeanu, Teng Joon Lim · IEEE Transactions on Communications · 2004
Iterative methods to solve a linear equation system can be used to derive multistage interference cancellers (ICs) that converge to the decorrelating or the minimum mean-square error linear detectors. The link between linear multistage IC and iterative solution methods is well known; however, the parameters needed for fastest convergence are functions of the eigenvalues of the channel matrix. In this letter, we propose new methods for finding optimal parameters without eigendecomposition.
