Abstract

The frequency division algorithm for multi-path ghost cancellation is described through the frequency-domain optimization method for analog and digital TV transmission. Some guidelines for the frequency division method are provided. A novel method to calculate the FIR and IIR coefficients of the deghost systems from the results of the frequency division is proposed. The simulation results are presented by using a Grand Alliance vestigial sideband channel model
