基于中继位置的自适应中继选择方案
Adaptive Relay Selection Scheme Based on Relay Location
摘要
Abstract
For the relay selection in cooperative communications,adaptive relay selection strategies are proposed for different power allocation schemes,where an additional relay can be employed when it is necessary.For Equal Power Allocation(EPA) among the source and relays,the search range of candidate relays can be effectively decreased by using the defined feasible two-relay region.For Optimal Power Allocation(OPA),the potential relays can be searched exhaustively by geometric programming.Numerical simulation results show that the proposed adaptive relay selection strategy with power optimization can significantly reduce the power consumption of the system compared with the traditional fixed selection strategy.关键词
