Abstract The behavior of the probability density function of the harmonic mean of two independent distributed non-negative random variables at the origin is analyzed. This result is then applied to study the performance of selection amplify-and-forward cooperation protocol in Nakagami fading channel and closed-form expression of the Symbol Error Rate (SER) in high SNR region is also provided. Both analytical and numeric results show that the selection amplify-and-forward cooperation protocol maintains the same diversity order as the conventional amplify-and-forward protocol, and has better SER performance.
