This description provides a method and device for dealing with interference, the method comprising: acquiring a time-domain signal of a physical random access channel PRACH within a target time period, and converting the time-domain signal within the target time period into a first frequency-domain signal , judging whether there is interference in the time domain signal in the target time period before the conversion according to the first frequency domain signal, and if there is interference, the data of the orthogonal frequency division multiplexing OFDM symbol corresponding to the time domain signal in the target time period Partially converted into a second frequency domain signal, setting frequency domain signals other than the frequency domain position corresponding to the second frequency domain signal to 0, to obtain a processed target frequency domain signal, converting the target frequency domain signal into a time domain signal domain signal to obtain the time domain signal after interference removal. Through this method, the interference signal in the PRACH signal can be removed.
Description
technical field [0001] The present disclosure relates to the field of wireless communication, and in particular to a method and device for dealing with interference. Background technique [0002] In a wireless communication system, wireless interference is generated in various ways. When the frequency domain resources allocated by different channels are adjacent at the same time, due to the reasons of the device itself, the limitation of filter out-of-band suppression, and the difference in signal generation methods between different channels, each channel will generate out-of-band radiation outside the working frequency band. Or generate spectrum leakage. These signals fall into the working frequency band of other channels and cause interference to them, usually including adjacent channel interference and co-channel interference. [0003] There will be a certain subcarrier guard interval between different channels, but due to the limited spectrum resources and the large fl...
