摘要

本文提出并研究了一种新型流量感知合作认知无线电网络，它可以在蜂窝系统中实现设备到设备（D2D）通信。通过为蜂窝传输提供中继合作，D2D 用户可以在许可频谱内实现自己的双向通信。与大多数现有研究不同的是，在所提出的网络中，无线供电的 D2D 用户都可以通过混合协议从基站（BS）接收射频信号来获取能量，该协议可以自适应地利用时间切换和功率分配技术。具体来说，D2D 用户执行解码前向操作来传输信号，而移动用户（MU）则采用选择组合技术。此外，通过推导 D2D 系统和蜂窝系统的精确中断概率和吞吐量表达式，评估了它们在拟议网络中的性能。数值和模拟结果验证了推导的正确性，并揭示了拟议网络中各种系统参数的影响。

Performance analysis in SWIPT-based bidirectional D2D communications in cellular networks

In this paper, a novel traffic-aware cooperative cognitive radio network that can enable device-to-device (D2D) communications in cellular system is proposed and investigated. By providing relay cooperation to cellular transmission, D2D users can realize their own two-way communication in the licensed spectrum. Unlike most existing works, in the proposed network, both wireless-powered D2D users can harvest energy via radio-frequency signals received from basic station (BS) through a hybrid protocol which can adaptively utilize both time-switching and powersplitting techniques. Specifically, D2D users perform decode-and-forward operation to transmit signals, and mobile user (MU) employs a selection combining technique. In addition, the performance of both D2D system and cellular system in the proposed network is evaluated by deriving the expressions of their exact outage probability and throughput. Numerical and simulation results validate correctness of derivations and reveal the influence of various system parameters of the proposed network.
