摘要
A digital filter with equalizers and a corresponding method for optimizing a linear equalizer of an RF transceiver determining filter characteristics of the specified analog filter, determining total signal filtering of the RF transceiver based upon a discrete time model of the specified analog filter and upon characteristics of the digital filter, determining an inverse of the determined total signal filtering; multiplying the inverse of the determined total signal filtering with the determined total signal filtering and optimally matching the desired equalizer filtering characteristic with an IIR magnitude equalizer to determine an optimal approximation of a magnitude response of the discrete time model of the specified analog filter. Thereafter, the method includes adding an inverse of the optimal approximation of the magnitude response and optimally matching the pre-distorting group delay response of the filter to obtain an optimal approximation to the pre-distorting group delay response of the filter.
