基于MABC的中继系统资源分配策略

针对MABC的中继系统，对资源配置策略的优化问题进行研究，并将功率分配问题和中继选择问题相结合。基于此，提出了一种存在干扰情况MABC模型的多中继系统资源分配策略（IS-MABC-OPOR）。考虑双向中继系统干扰信号对其传输性能的影响，以通信链路信道容量最大化为优化目标，利用拉格朗日方法，对通信链路上的各节点进行了最优功率分配和最佳中继选择，给出了通信链路信道容量最大意义下的资源分配数学表达式。仿真结果表明，该链路的信道容量受中继节点位置以及链路总功率的制约，相比于等功率分配方案（EPA）、随机功率分配方案（RPA）和在所提方案的基础上加大干扰信号的信道增益，IS-MABC-OPOR方案有效提高了系统的信道容量，从而实现资源能够满足更高速率的业务传输需求。

Resource allocation strategy of relay system based on MABC

Aiming at the relay system of MABC, this paper studied the optimization of resource allocation strategy, and combined the power allocation problem with relay selection problem. Based on this, the paper proposed a multi-relay system resource allocation strategy(IS-MABC-OPOR) with interference MABC model. Considering the influence of interference signals on the transmission performance of two-way relay system, and aiming at maximizing the channel capacity of communication links, optimal power allocation and optimal relay selection for each node on the communication link used the Lagrangian method, and gave the mathematical expression of resource allocation under the maximum channel capacity of the communication link. The simulation results show that the channel capacity of the link is constrained by the relay node location and the total power of the link. Compared with the equal power allocation scheme(EPA), the random power allocation scheme(RPA) and the channel gain of the interference signal on the basis of the proposed scheme, the IS-MABC-OPOR scheme effectively increases the channel capacity, thereby realizing resources to meet higher-speed service transmission requirements.
