1.2. Our Contribution
- A dynamic power allocation optimization strategy based on channel quality and target rate is proposed to ensure that relay nodes provide relay services on the premise of successful decoding source information.
- The optimal relay selection based on statistical and perfect CSI are proposed. The exact analytical outage probability of the proposed algorithms are derived by using order statistic tool.
- The performance of the proposed algorithm is verified by numerical simulation and Monte Carlo Simulation. The results show that the performance of the proposed scheme is better than that of traditional max–min algorithm.
