Abstract
In order to improve the equalization convergence performance for single-carrier broadband signals, an equalization technology based on subband is discussed. Two broadband nonlinear equalization structures with switch modes are proposed by using complex-valued subband filterbanks and decision feedback equalizer. The update iterative formulae of these two structures are deduced based on least mean square algorithm. Their convergence characteristics are analyzed in different equalization modes. Simulation experiments show that these two structures can be used in group delay channel. Compared to conventional equalization they have better convergence performance and lower calculation complexity.关键词
