Abstract
Closed form expressions for the PDF and MGF of the harmonic mean of two independent exponential variates are cited and derived, and then applied to study the performance of cellular multi-node and dual-hop cooperative communication systems with non-regenerative relays over flat Rayleigh fading channels. We derive the probability density function (PDF) and asymptotic symbol error rate (SER) expression with MRC scheme. Then we use Matlab to simulate the performance.
Highlights
MIMO technique has been regarded as the essential technique for beyond 3G mobile cellular networks
The bottleneck of capacity is limited and the diversity technique of mobile terminals could not be realized from the traditional end-to-end transmission systems
We can find on the same SNR, the performance is better when the relay number is more
Summary
MIMO technique has been regarded as the essential technique for beyond 3G mobile cellular networks. The Benefits of MIMO system have been extensively studied by researchers in both academic and industry. Mazen O Hasna et al in [3,4] firstly applied the harmonic mean to the cellular multi-node and dual-hop cooperative communication systems. They respectively derived the probability density function (PDF), the cumulative distribution function (CDF) and the moment generating function (MGF) of the expression. This paper applied the method of the harmonic mean to derive PDF and MGF of two independent exponential variates are cited and derived to study the performance of cellular multi-node and dual-hop cooperative communication systems with non-regenerative relays over flat Rayleigh fading channels
