A wideband blind linear equalizer based on non-uniform subband decomposition is proposed in this paper.The key feature is that it utilizes the idea of power spectrum amplitude segmentation to perform the non-uniform subband decomposition,and optimizes the choice of the non-uniform subband filter coefficients,thus obviously improves the convergence speed of the blind linear equalization algorithm.In addition,the updating strategy of subband equalizer's coefficients is discussed,and an effective trade-off between the convergence speed and computational complexity is presented.Theoretical analysis and simulation results prove the efficiency of the proposed wideband blind linear equalizer.
