Abstract

This paper presents an efficient method for computing the optimal tap coefficients of the MIMO equalizers and cancellers from the channel impulse responses (CIR). The proposed method provides an insight of the minimum mean-square error (MMSE) solution in a general MEMO system and shows that the MSE optimization problem in a M-input N-output system can be decomposed into N independent minimization problems each with smaller size. Solving each separate problem in MMSE sense is computationally efficient, thus leading to substantial savings in overall computational complexity. Compared with a prior method, this new method is exact and much faster,
