Selection of Cooperative Node and Power Allocation Scheme Based on DF
基于DF的协作节点选择及功率分配策略研究

For wireless communication systems, especially for single antenna node wireless communication systems, cooperative communication techniques can improve system performance effectively. Selection of cooperative node and cooperative scheme are two basic problems for cooperative communication. For the goal of capacity maximum, based on DF, the problems including selection of cooperative node and power allocation scheme are researched this paper, results show that when certain conditions are satisfied and reasonable power allocation scheme is adopted system capacity can be improved availably.
