Abstract :
We analyze the effect of the loopback signal on the equalization digital on-channel repeater (EDOCR) used for single frequency network (SFN), and propose a simple loopback canceller. Simulation results show that the proposed loopback canceller improves the convergence performance of the decision feedback equalizer (DFE) in the EDOCR by eliminating the loopback signal in advance instead of the DFE.
