Abstract :
As CMMB network is single-frequency network (SFN), the feedback cancellation of digital on-channel repeater becomes an outstanding problems about network coverage. But the traditional digital on-channel repeater has more inter-symbol interference (ISI), so this paper puts forward an equalized digital on-channel repeater (DOCR), which can effectively correct the ISI, synchronization the input and output, and improve the isolation between the receiving antenna and transmitting antenna.
