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, we propose an efficient equalizer algorithm for the cellular relay system, which uses the DFE combining the LDPC code. The proposed equalizer helps to compensate RF impairments and improve better performance than used independently. In addition, proposed equalizer has less iterative number of LDPC code. So, the proposed equalizer system has low complexity. Therefore, in this paper, BER performance of DFE combining the LDPC code for cellular relay system is satisfied with 4.3dB at 10-4.
