Abstract

The invention discloses a spectrum interference detection device and method. The device includes: a receiving antenna for receiving space signals; a normal signal processing unit for filtering and low-noise amplification of the normal signals, and sending them to the radio frequency processing unit; an interference signal processing unit for preprocessing the interference signals , and send it to the radio frequency processing unit; the radio frequency processing unit is used for performing radio frequency processing on the received normal signal, and performing radio frequency processing on the preprocessed interference signal in the idle time slot; the radio frequency sampling unit is used for sampling according to the input The clock performs radio frequency sampling on normal signals, and performs radio frequency sampling on interference signals after radio frequency processing in free time slots, and sends the interference signals after radio frequency sampling to the interference signal detection unit; the interference signal detection unit is used to detect radio frequency The sampled interference signal is subjected to fast Fourier transform in the digital domain to identify the frequency band and obtain the communication system of the interference signal.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a spectrum interference detection device and method. Background technique [0002] With the continuous development of communication technology, various countries currently use several different communication systems to build networks together. In order to facilitate network installation and save costs, the demand for wireless broadband base stations that can be applied to different communication systems is increasing. However, since the receiving and processing bandwidth of this wireless broadband base station is too wide, it is easily interfered by space. In actual use, it is best to collect and analyze various wireless spectrum signals in space for better frequency planning. Therefore, there is an urgent need for a detection device and detection method for spectrum interference of wireless broadband base stations, which can extract, process and analyze various interference ...
