Abstract本发明涉及一种安全高能效的认知D2D通信方法,小蜂窝基站和认知用户分别进行信道质量评估;建立关于无线充电功率和无线充电时间的联合资源分配模型;采用迭代优化算法计算最优资源分配结果;以最优无线充电功率发射射频信号;认知用户在最优无线充电时间内收集射频信号能量;小蜂窝基站以最优无线充电功率干扰窃听者,认知用户设置自身的最大可行发射功率,并进行认知D2D通信。本发明面向超密集小蜂窝网络,在利用认知无线电技术实现频谱共享,并采用能量收集技术为认知用户进行无线充电的同时,通过人工噪声对窃听者进行干扰,可以实现安全高能效的认知D2D通信,有效提高频谱效率、能量效率以及物理层安全。
Other AbstractThe method involves separately performing channel quality assessment by a small cell base station and a cognitive user. Channel power gain between links is determined. The channel power gain is transmitted to a small cell base station. A joint resource allocation model is established by a small cell base station for wireless charging power and wireless charging power time. Optimal wireless charging power and optimal wireless charging time are calculated by the small cell base station using iterative optimization algorithm. A radio frequency signal is transmitted to the small cell base station according to optimal wireless charging power. Optimal wireless charging power is obtained by the small cell base station. Maximum interference power is collected by ordinary users by cognitive users based on energy to determine maximum feasible transmit power and perform cognitive communication.
