This letter investigates the outage performance of dual-hop amplify-and-forward (AF) cooperative networks in the presence of multiple co-channel interferers at both the relay and destination nodes and subject to non-identically distributed Nakagami-m fading. A simple, easy-to-compute, highly accurate closed-form approximate expression for the end-to-end outage probability is derived. Such expression is written in terms of finite sums of the product of Meijer's G-functions, and is evaluated instantaneously regardless of the number of interferers, drastically contrasting with the intricacy and computational inefficiency inherent to the exact formulation. The tightness of our proposed methodology is attested through Monte Carlo simulation results.
