A novel initialization scheme for blind equalization algorithms
S. Xanthopoulos, Anthony George Constantinides · 2003
A new algorithm for equalizer initialization for blind equalization algorithms is presented. The proposed algorithm initially employs a heuristic approach in order to obtain an estimation of the channel's characteristics. Then, through a least squares inversion, an approximation of the channel's estimate inverse is produced and is used to initialize the equalizer's tap weights. The proposed algorithm exhibits superior performance compared with the center-tap initialization scheme in terms of convergence speed, shorter required equalizer lengths and lower bit error rates.
