Embodiment Construction

[0027] figure 2 It is a flowchart of a standing wave detection method provided by an embodiment of the present invention. The detection method includes:

[0028] Step 21, sending the baseband multi-tone signal. Specifically, such as image 3 As shown, the baseband multi-tone signal is the baseband signal of the multi-tone signal. Then convert the baseband multi-tone signal to radio frequency, that is, the signal source sent by the base station uses a multi-tone signal source to replace the traditional FDR frequency sweep signal source. The form of the baseband multi-tone signal is not limited, that is, parameters such as the frequency point interval and the number of frequency points can be completely determined according to the actual system capability and the requirements for detection accuracy.

[0029] Step 22, receiving the feedback signal of the baseband multi-tone signal from the feedback channel;

[0030] Step 23, using the feedback signal and the baseband multi-...

Abstract

The invention relates to a standing wave detection method, a standing wave detection device and a base station. The standing wave detection method comprises the following steps of: transmitting a baseband multi-voice signal; receiving a feedback signal of the baseband multi-voice signal from a feedback channel; acquiring a time domain system transmission function by using the feedback signal and the baseband multi-voice signal; and acquiring a standing wave detection value according to the time domain system transmission function. By taking the baseband multi-voice signal as a transmitting signal used in a test, namely a baseband signal, receiving the feedback signal through the feedback channel and acquiring the time domain system transmission function by using the transmitting signal and the feedback signal, the standing-wave ratio and the cable fault point position are obtained by only increasing a little software algorithm but not increasing the hardware cost, and the standing wave detection and the breakpoint positioning of an antenna port cable are realized. Meanwhile, a plurality of conventional wireless products can realize the function through software update, and maintenance and detection personnel detects and positions faults without carrying heavy and expensive instruments, and performs standing wave detection without detaching cable joints.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a standing wave detection method, a standing wave detection device and a base station. Background technique [0002] In the field of wireless communication technology, wireless communication products such as base stations need to check the quality of products through standing wave detection to ensure the signal quality in the communication process. [0003] In the prior art, the standing wave detection is implemented by a frequency domain reflectometry (Frequency Domain Reflectome-try, FDR) method or a phase-detection frequency-domain re-flectometry (PDFDR) method. Among them, FDR is also called frequency sweep reflectometer, which is used to send continuous and step sine wave, transmit through the discontinuous point of the transmission cable, and receive the transmitted step continuous wave; by detecting the difference between the transmitted signal and the refle...
