- We consider equalizer initialization problems when the transmitted symbol rtate is higher than the available channel bandwidth. In this case, the coefficients of an adaptive equalizer in the receiver can be updated only once per a predefined symbol period, requiring unacceptably long training time. The training time can be reduce significantly if the equalizer begins the training process from a properly initialized condition. In this letter, a fast initialization method is analytically designed for a minimum mean squared error(MMSE) type equalizer. Finally the initialization performance is verified by computer simulation.
