基于候选解集合的多中继选择算法
Multi-relay Selection Algorithm Based on Candidate Solution Set
协作分集技术是当前和未来无线通信的热点，其中节点选择问题受到了各界学者的广泛关注。本文在已知信道状态信息的前提下，针对单发多收协作通信场景，为保证中继节点选择的公平性，以信噪比和能效（信噪比/总功率）为优化目标，提出了一种基于候选解集合的多中继选择算法：为每个用户选择一组最佳候选中继作为候选解集合，将单发多收中继协作场景转化为多个单发单收中继协作场景。在此场景下，提出了一种最优中继排序算法，为每个用户选取具有最优信噪比的中继节点集合进行协作。仿真结果验证了该算法的可行性。
In the scene of single-iput-multi-output (SIMO), under the premise of known channel state information, taking the SNR and energy efficiency (SNR/Total Power) as the optimal objectives, we propose a multi-relay selection algorithm based on candidate solution set: the algorithm selects a optimal candidate relay set for every user to ensure the fairness of node selection. The simulation results demonstrate the feasibility of the algorithm.
