Abstract

The invention relates to a safe and high-energy-efficiency cognitive D2D communication method. The method comprises the steps of performing channel quality evaluation on a small cell base station andcognitive users; establishing a joint resource allocation model about wireless charging power and wireless charging time; calculating an optimal resource distribution result by adopting an iterative optimization algorithm; transmitting the radio frequency signal at the optimal wireless charging power; the cognitive user collects radio frequency signal energy within the optimal wireless charging time; and the small cell base station interferes with the eavesdropper with the optimal wireless charging power, and the cognitive user sets the maximum feasible transmitting power of the small cell base station and performs cognitive D2D communication. The method is oriented to an ultra-dense small cellular network; the cognitive radio technology is used for achieving spectrum sharing, the energy collection technology is used for conducting wireless charging on cognitive users, meanwhile,interference is conducted on eavesdroppers through manual noise, safe and high-energy-efficiency cognitive D2D communication can be achieved, and the spectrum efficiency, the energy efficiency and the physical layer safety are effectively improved.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a safe and energy-efficient cognitive D2D communication method. Background technique [0002] The scarcity of spectrum resources and the continuity of energy supply have always been important challenges faced by wireless communication systems. Therefore, academia and industry have always been committed to improving the spectrum efficiency and energy efficiency of wireless communication systems. Ultra-dense networks (Ultra-Dense Networks) and device-to-device communication (Device-to-Device, D2D), as an effective method to improve spectral efficiency and network capacity, and reduce terminal energy consumption, have become the fifth generation (5G) mobile communication The key technology of the system. The so-called ultra-dense network is to make the network dense by deploying a large number of small cell base stations (Small Cell Base Station, SCBS). In this way, on ...
