Embodiment

[0055] 1. Establish the system model and set the system parameters

[0056] The example study of the present invention includes a single cell system of a single transmitter, user and eavesdropper, and the system model established is as follows figure 1 shown. Among them, the cell base station is equipped with N antennas to form an equidistant linear array, and its structure is as follows figure 2 As shown, the number of antennas will directly affect the concentration of the main lobe power and the status of the poles and zeros of the side lobes. In this embodiment, N=9. In actual situations, the number of antennas can generally be several to tens of antennas. Normally, the base station will only provide communication services to users within the scanning range. In this embodiment, the scanning range is set to (-90°, 90°). When setting the distance between adjacent antennas, since the wavelength (frequency) of the RF signal is generally fixed and the scanning range has been ...

Abstract

The invention discloses a method for implementing an optimal confidentiality throughput and high-efficiency energy collection in a SWIPT (Simultaneous Wireless Information and Power Transfer) system.According to the method for implementing the optimal confidentiality throughput and high-efficiency energy collection in the SWIPT system, a confidentiality throughput of a legal user is calculated, athreshold is set to judge whether confidentiality interruption occurs so as to calculate a confidentiality interruption probability, and by regulating a target confidentiality rate and a power distribution ratio of a transmitting terminal, the optimal confidentiality throughput is obtained; and a receiving terminal adaptively regulates a power distribution coefficient according to received powerand information decoding sensitivity and only provides power which meets the decoding requirement for information decoding, and other power is all used for energy collection. The method solves the problems of low confidentiality throughput and low energy collection efficiency when an eavesdropper exists in an existing SWIPT system.

Description

【Technical field】 [0001] The invention belongs to the technical field of wireless energy carrying, and in particular relates to a method for realizing optimal confidentiality throughput and efficient energy collection in a SWIPT system. 【Background technique】 [0002] With the prosperity and development of wireless communication networks, the number of wireless communication devices has increased dramatically. Constrained by the battery capacity of the device, its working time is also limited. In order to extend the service life of these portable devices, we can make communication devices collect electromagnetic energy in the environment while receiving information, and use the collected energy to power themselves to extend the service life of the devices. [0003] At the same time, the Simultaneous Wireless Information and Power Transfer (SWIPT) system is a combination of wireless energy transfer and wireless communication. Under the premise of ensuring the normal communic...
