General Multi-Branch Multi-Hop (MBMH) cooperative diversity systems with Decode-and-Forward (DF) relays are investigated on non-identical Nakagami-m fading channels in the presence of an arbitrary number of non-identical co-channel interferers. This paper presents exact closed-forms for the probability density function of the signal-to-interference-plus-noise ratio and the outage probability of a DF MBMH cooperative relaying system. The results show that the performance of the DF MBMH cooperative relaying system is more vulnerable when co-channel interferers are closer to the destination than when they are closer to the relays. The authors' analytical results are verified by Monte Carlo simulations.
