| 英文摘要: |
| The performances of selection cooperation are investigated over asymmetric fading channels where the source-relay and the relay-destination channels experience Nakagami-m and Rayleigh fading, respectively. Decode-and-forward (DF) protocol is adopted and the Nth best relay is selected from M available relays. Probability density function (PDF) for the instantaneous signal-to-noise ratio (SNR) at the destination is derived first. Then, it is used to derive the exact expressions for outage probability and average symbol error rate (SER). The results hold for arbitrary M or N. Finally, simulations are carried out to verify the correctness of our theoretical analysis and results show that M and N almost have the same effect on the performance of outage probability and SER. |
