Embodiment Construction

[0041] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0042] In the prior art, for the systems (for example, wireless communication systems) that need to detect the standing wave ratio, the detection of the standing wave ratio is carried out by the scalar detection method of the standing wave ratio. However, due to the use of the scalar detection method of the standing wave ratio When , at least three assumptions are required to be used, but in the actual application environment, it is difficult to satisfy these three assumptions at the same time, thus resulting in low accuracy and inaccuracy of the obtained standing wave ratio.

[0043] In this embodiment, a standing wave ratio acquisition method is provided, which is applicable to various fields (for ...

Abstract

The invention discloses a standing wave ratio acquisition method and device. The method includes: separately obtaining the vector expressions of the physical attribute values ​​of the incident signal and the reflected signal; abstracting the standing wave ratio detection device into a vector model, and the corresponding physical The parameter value of the expression includes the physical property value of the incident signal and the physical property value of the reflected signal represented by the vector, and the value of the expression corresponding to the vector model is the reflection coefficient, where the reflection coefficient is a vector value; the standing wave is obtained according to the reflection coefficient Compare. The invention improves the accuracy of standing wave ratio detection.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method and device for obtaining a standing wave ratio. Background technique [0002] In communication technology, the standing wave ratio is used to measure the impedance matching in the signal transmission link. The standing wave ratio is defined by the magnitude of the reflection coefficient, as follows: [0003] Suppose the forward wave (also known as the transmitted wave) is V f , reflected wave V r , then the reflection coefficient is defined as: It should be noted that Γ is a complex vector describing the magnitude and phase of the reflection. [0004] According to the definition of standing wave ratio: [0005] VSWR = 1 + ρ 1 - ρ . . . . . . ...
