Abstract :
This paper presents a robust decision-feedback equalization method for 8-VSB DTV receivers under severe channel environments where a 0-dB ghost exists. Noncausal filtering is employed to make a severe channel be mild. Simulation results show that the proposed method has more stable convergence than existing decision-feedback equalization schemes.
