In this paper, a repeater system is studied which is basically used for the relay in the cellular communication. The LDPC (Low Density Parity Check) code is introduced into DFE (Decision Feedback Equalizer) in the receiver for the BER (Bit Error Rate) performance. For the better Quality-of-Service (QoS) and the higher convenience, the wireless repeater was considered for the relay system. In this paper, the authors propose an efficient equalizer algorithm for the cellular relay system, which uses the DFE combining the LDPC code.
