摘要

本文研究了在PU碰撞约束下的能量收集协同认知无线电(CR)网络。如果主用户(PU)仍然存在于给定信道中，则在该信道中合作传输的cr的最优数量;否则，所有cr都以时分方案传输自己的数据。在CR处收获的能量分为两部分，一部分分配给PU合作传输，另一部分用于自身传输。能量的分配基于目标CR吞吐量。在PU随机行为下，研究了能量分配参数和感知时间对吞吐量性能的影响。

Throughput Analysis of a Energy Harvesting Cooperative Cognitive Radio Network

In this paper, energy harvesting cooperative cognitive radio (CR) network is studied under a collision constraint of PU. Optimal numbers of CRs cooperate in transmission of primary user (PU), if it remains present in the given channel; otherwise all the CRs transmit their own data in time division scheme. The harvested energy at CR is divided into two parts, one part is allocated for cooperation in PU transmission and the other part is used for its own transmission. The allocation of energy is based on the targeted CR throughput. Influence of an energy allocation parameter and sensing time on throughput performance is studied under the random behaviour of PU.
