Abstract

The invention discloses a frequency-spectrum scanning device and a method thereof. The device comprises a back end equipped on a base station system and is characterized in that the device further comprises a frequency-spectrum collection / storage module for the real-time collection and storage of frequency-spectrum amplitude corresponding to each user carrier frequency; a processor for reading out the value of the frequency-spectrum amplitude, processing and packaging the value of the frequency-spectrum amplitude by a first software module, and then transmitting the processed and packaged results to a second software module equipped on the back end for the next processing; and a display unit for displaying the frequency-spectrum curve obtained after the processing by the second software module. The invention solves the problem that the prior base station system fails to display the frequency-spectrum curve of user carrier frequency by using software, and has the advantages of low hardware cost and reduced labor and material costs.

Description

technical field [0001] The invention relates to technologies such as baseband signal modulation in the communication field, in particular to a method and device for spectrum scanning by combining software and hardware. Background technique [0002] With the development of communication technology, operators have continuously increased requirements on the reliability and ease of use of communication systems. When the base station is working normally, the stability and anti-interference of the user carrier frequency are particularly important. Therefore, it is necessary to regularly observe the carrier frequency of the user to ensure that there is no other interference near the carrier frequency to ensure the user's call quality. Under the existing circumstances, it is difficult to realize these requirements. Usually, the carrier frequency of the base station can be observed by using a spectrum analyzer, but the base station is always very scattered and remote, and the spect...
