文章主要在Nakagami-m信道环境下研究了基于增量中继的机会选择的中断概率和吞吐量性能。在各个信道为独立非同分布条件下,推出了基于增量中继的放大转发机会选择的中断概率和吞吐量的近似表达式。通过仿真验证了中断理论值是一个下界,同时通过仿真发现基于增量中继的放大转发机会选择机会比传统的放大转发机会选择的吞吐量要高。
The article mainly studies the outage probability and throughput performance of opportunistic selection based on incremental relay in Nakagami-m channel environment. Under the conditions of independent and non-uniform distribution of each channel, an approximate expression of the outage probability and throughput of amplification forwarding opportunity selection based on incremental relay is proposed. The simulation results show that the theoretical value of the interrupt is a lower bound, meanwhile, it is found through the simulation that the opportunity of choice of amplification and forwarding opportunity based on incremental relay is higher than the throughput of traditional choice of amplification and forwarding.
