<FONT face=Verdana>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.
