An analytical approach is used to derive bit error rate for LDPC coded-optimum combined (LDPC-OC) system in the presence of only single co-channel interferer. A probability density function has also been derived using moment generating function for optimum combining with one interferer. This paper considered that signal is BPSK modulated and transmitted over i.i.d Rayleigh fading channel. The analytical result shows that for BER 10 -2 , the LDPC-OC system provides an additional gain of 4.1 dB
