In this paper, the average bit error rate (ABER) performance of dual-hop decode-and-forward (DF) cooperative systems with co-channel interference at both the relay and destination nodes is analyzed in Nakagami-$m$ fading channels with arbitrary (integer as well as non-integer) values of $m$. This channel condition is assumed for both the desired signal as well as co-channel interfering signals. In addition, the practical case of unequal average fading powers between the two hops is assumed in the analysis. Accurate closed-form approximate expressions for the BER performance of different modulation schemes, specificlly differential binary phase shift keying (DBPSK) and non-coherent binary frequency shift keying (NCBFSK), are derived. The analysis assumes an arbitrary number of independent and non-identically distributed (i.n.i.d.) interfering signals at both relay (R) and destination (D) nodes. The derived closed-form expressions are simple and easy to evaluate as compared to the simulation.
