提出了一种放大转发网络中的中继选择方案,假设目的节点配置多个天线,源节点和所有中继节点都配置单个天线,方案选择一组中继同时在相同的频带上放大转发接收到的源节点信息以最大化接收信噪比。与只择一个最优中继的方案相比,方案在保持满分集阶数的情况下获得了更高的中断容量和更优的误符号率性能。与只选择一个最优中继的方案相比,在0.000 01的误符号率水平上,少需要发射功率1.6 dB。
Propose a repeater option in the amplification and forwarding network. Assuming that the destination node is configured with multiple antennas, the source node and all the relay nodes are configured with a single antenna. The scheme selects a group of relays and amplifies, forwards and receives them in the same frequency band Source node information to maximize the received signal-to-noise ratio. Compared with the scheme that only one optimal relay is selected, the scheme achieves higher interrupt capacity and better error symbol rate performance while maintaining full diversity order. Compared with the scheme of choosing only one best relay, the transmit power of 1.6 dB is less required at the symbol error rate of 0.000 01.
