Embodiment Construction
[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the present application 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 application, and are not intended to limit the present application.
[0046] The phase deviation correction method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the base station 104 through the network. For example, the base station receives a target signal sent by a terminal at a preset location to obtain a real received signal. Among them, the terminal 102 can be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and the base station 104 can be realized by an i...

The present application relates to a phase deviation correction method, device, computer equipment and storage medium, and relates to the field of positioning technology. The method includes: receiving a target signal sent at a preset position to obtain a real received signal; according to the preset position, determining an ideal received signal obtained by the base station receiving the target signal under ideal conditions; and obtaining an ideal received signal according to the real received signal and the ideal received signal , and the relationship between the phase deviations, using the method of subspace decomposition to determine the phase deviation, wherein the phase deviation is used for the base station to perform phase compensation on the received signal of the base station, and according to the received signal after phase compensation, determine the terminal corresponding to the received signal s position. By adopting the method, the phase deviation of the base station can be corrected, and the process is simple and easy to realize.
Description
technical field [0001] The present application relates to the technical field of positioning, and in particular to a phase deviation correction method, device, computer equipment and storage medium. Background technique [0002] Due to the development of the Industrial Internet and the Internet of Things, the demand for user positioning in 5G communications has become increasingly prominent. In practical applications, due to the existence of unideal factors such as antenna design, antenna mutual coupling, and assembly accuracy, anisotropic deviations occur between antenna units, which makes the base station unprepared for terminal positioning. Therefore, it is necessary to calibrate the phase deviation of the base station lack. [0003] In the traditional method, the phase deviation of the base station is usually corrected by an off-line darkroom method. Specifically, the darkroom offline method usually places the base station in an offline darkroom environment, then locat...
