Title:
VECTOR STANDING WAVE RATIO ACQUISITION METHOD, FPGA AND REMOTE RADIO FREQUENCY UNIT
Document Type and Number:
WIPO Patent Application WO/2019/001279
Kind Code:
A1
Abstract:
Provided are a vector standing wave ratio acquisition method, a field programmable gate array (FPGA) and a remote radio frequency (RF) unit, wherein an amplitude value of a reflection coefficient of each signal period is directly calculated (S104) by means of acquiring maximum amplitude values of a pulse emission signal and a reflection signal during each signal period (S101, S102); directly calculating a phase of the reflection coefficient of each signal period (S105) by means of acquiring a time delay of the pulse emission signal and the reflection signal during each signal period (S103) and combining the same with a preset acquisition frequency; determining the reflection coefficient of each corresponding signal period according to the amplitude and phase of the reflection coefficient of the each corresponding signal period (S106), and obtaining the vector standing wave ratio of the each corresponding signal period according to the reflection coefficient (S107).
