| Abstract: | The paper describes a fast start-up equalizer which firstly uses the semi-extended Neuman-Hoffman sequence to estimate the time varying channel impulse response, and then a initial DFE tap value to preload the the equalizer. The performance of the equalizer is confirmed by simulation in the 802.16 channel model, and it is fund that the convergence speed is comparable with the recursive least squares (RLS) adaptive algorithm. |
