Abstract :
This paper presents an equalization on-channel repeater (OCR) for terrestrial-digital multimedia broadcasting (T-DMB) system of Korea. The proposed OCR uses a time-domain equalizer based on adaptive complex FIR filtering to remove a feedback signal due to incomplete antenna isolation and multipath signal existing between a main transmitter and the OCR. This makes it possible to emit a high-power error- corrected signal from the OCR.
