任品毅, 权良辉. Adaptive Reduced-Rank Linear Equalization of Multiple Input Multiple Output Frequency Selective Channels Based on Multistage Wiener Filter[J]. 2008, 42(2): 218-221+260.DOI:
an reduced-rank adaptive equalizer for multiple input multiple output systems was proposed. The proposed algorithm uses the multistage Wiener filter to compute the base vectors of a subspace
and the output of the equalizer is then restricted in the lower-dimensional subspace by projecting input vectors into the subspace. Thus
the computational complexity is reduced and the convergence rate is increased. Theoretical analysis and simulation results show that the convergence rate of the proposed method is significantly faster and the computational complexity is much lower than existing adaptive algorithms. The proposed algorithm can achieve near full-rank mean square error performance with filter rank no more than 10.
