Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] In view of the deficiencies and defects of the existing optimal relay position search algorithm for UAVs, namely: (1) the source (S) and the destination (D) need to use their own GPS function to measure their own position information and send the information to For mobile relay, relying on GPS function is vulnerable to attack and interference, resulting in location search failure; (2) For communication equipment without GPS function or GPS has been damaged, some existing algorithms cannot be used; (3) Airborne multiple Compared with a single antenna, the antenna increases the complexity of t...

Abstract

The invention is suitable for the technical field of wireless communication and provides a searching method of an optimum relay position of a moving relay based on a reverse compensation mechanism. The method comprises the steps that: the moving relay receives a testing signal from a source end on the current position of a fixed track, carries out amplification and forwards the testing signal to a target end; B, according to the received signal, the target end calculates communication performance, generates single-bit information according to the calculation result, and feeds the single-bit information back to the moving relay; C, according to the fed single-bit information, the moving relay calculates the position at the next moment and moves to the position at the next moment; and the steps A-C are repeated until an optimum relay position is finally determined. By adopting the searching method and system, the relay communication performance is improved, the position information of the source end and the target end are not needed, a plurality of antennas are not needed, the moving relay can find the optimum relay position in a given moving lotus range only by utilizing the single-bit information fed back by the target end.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a search method and system for an optimal relay position of a mobile relay based on a reverse compensation mechanism. Background technique [0002] The communication relay is used to forward the information sent between different nodes, which expands the communication range and improves the performance of the communication system. Land radio communications are easily blocked and shielded by obstacles, and aircraft, satellites, and UAVs (Unmanned Aerial Vehicles, UAVs) can act as communication relays, because airborne relays can effectively communicate with each other in rugged mountainous areas or urban areas The two parties establish a connection. In recent years, the problem of using UAVs as communication relays has attracted the attention and research of many scholars, and its applications are also very extensive. [0003] The existing algorithms a...
