The outage probability of an efficient signal space cooperative (SSC) scheme is investigated over general independent and non‐identically distributed Nakagami‐ m fading channels. In particular, the exact outage probability expression is derived for arbitrary values of the fading parameter m ( m ≥ 0.5). Furthermore, an asymptotic approximation for the outage probability is obtained, which clearly shows the diversity and coding gains of the SSC scheme, and therefore can offer important theoretical guidance to scheme designers. Simulation results are provided to verify the theoretical analysis.
