Problems solved by technology

The key problem with this method is that if there is a physical change in the channel between the base station or WIFI AP and the terminal, such as the opening or closing of a window, its channel characteristics will change and positioning may fail, so it is only suitable for indoor space environments Relatively stable occasions

Abstract

The embodiment of the invention provides a signal processing method, a signal processing device and signal processing equipment. The method comprises the steps that the signal processing device emits multiple first signals which are mutually orthogonal in multiple directions; multiple second signals which are formed by propagating the first signals through at least one non-air dielectric are received; according to the first signals and the second signals, the multi-dimensional space characteristics of the position where the signal processing device is located are determined, and the multi-dimensional space characteristics are used for determining the position where the signal processing device is located. The signal processing method, the signal processing device and the signal processing equipment provide a signal processing scheme capable of being used for assisted positioning.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a signal processing method, device, and equipment. Background technique [0002] In recent years, with the rapid rise of location-based services (Location-based Services), many types of indoor positioning technologies have emerged. [0003] In order to strike a balance between positioning accuracy, accuracy, and implementation difficulty, some recent research proposes to use the signal sent by the base station or WIFI access point (AP for short) to calculate the distance between the base station or WIFI AP and the terminal. The characteristics of the transmission channel are used as a fingerprint to identify the location of the terminal, and compared with the fingerprint stored in the database in advance, so as to achieve the purpose of indoor positioning. The key problem with this method is that if there is a physical change in the chan...
