Benefits of technology

This patented technology allows for efficient wireless data transfer over mm waves (WB) networks while maintaining privacy by preventing unwanted communications from happening outside their intended range or causing harmful side effects such as jamming devices inside them. It also enhances secure reception when transmitting important messages like voice calls due to its ability to block out noise caused by other nearby paging stations. Overall, this innovation helps improve overall performance and efficiency within these systems.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the efficiency and effectiveness of securitized access (SAA) communications over milliwave networks without compromising their integrity or privacy concerns. Current methods such as encryption techniques require significant effort during installation and maintainment processes, making them difficult to implement within practical limits. There is thus a challenge towards developing efficient and effective ways to transmit data wirelessly between devices located far away worldwide through these types of infrastructure like 5G.

Embodiment

[0108] Simulation experiments have verified the effectiveness and realizability of the patented switching scheme. The transmission power P used in this embodiment t =30dBm, noise power σ 2 =-100dBm, number of base station antennas N b =3, path fading index α L = 2.1, α N =3.5, the base station beamforming side lobe to main lobe gain ratio x=0.2. In the numerical simulation, k (k=4) users are randomly distributed each time, and the interference noise power of each group is realized 1000 times.

[0109] figure 2 The computer simulation results of the method of the present invention are given, and compared with non-blocking communication, only cooperative user interference blocking and full-duplex base station interference blocking schemes. The simulation parameters under these four methods are exactly the same, and the abscissa in the figure represents the interference noise power (cooperative user transmission or base station transmission). It can be seen from the figure t

Abstract

The invention provides an interference blocking scheme switching method for millimeter wave cellular network uplink secure transmission. The interference blocking scheme switching method specificallycomprises the following steps: the step 1, taking an optimal cooperative user in K-1 cooperative users to carry out interference blocking and taking full duplex interference blocking of a base stationas an interference blocking scheme respectively; the step 2, calculating the safety throughput of a communication link when the K-1 cooperative users in the step 1 interfere, and taking the cooperative user corresponding to the maximum safety throughput as an interference node of an interference blocking scheme, meanwhile, calculating the safety throughput during full duplex interference of the base station in the step 1; and the step 3, comparing the communication link security throughput obtained in the step 2 with the communication link throughput when the base station interferes, and taking the interference blocking scheme corresponding to the maximum security throughput as the interference blocking scheme of the current time slot; According to the invention, the safety throughput istaken as an evaluation index, and the user position information is utilized to efficiently and flexibly switch between the two interference blocking schemes, so that the system always works in an environment with the optimal safety throughput.
