Background technique
In traditional cellular communication, communication equipment uses the communication mode of HD (Half Duplex, half-duplex), that is, communicates
Equipment can only send or receive wireless signal in the given time of given frequency, and cannot transmitting/receiving wireless signal simultaneously.Recently,
FD (Full Duplex, full duplex) communication becomes a research hotspot, i.e. communication equipment is same in the given time energy of given frequency
When transmitting/receiving wireless signal.The equipment for supporting FD communication uses one or more kinds of disturbance restraining methods to send signal docking to reduce
The self-interference of the collection of letters number, possible interference suppression algorithm includes that passive interference elimination is eliminated with active interference, wherein passive interference
It eliminates mainly by increasing the isolation reduction self-interference of dual-mode antenna, it includes simulation elimination and number that active interference is eliminated again
It eliminates.
In 3GPP (3rd Generation Partner Project, third generation cooperative partner program) LTE system, up and down

The frequency-region signal received executes IFFT (Inverse fast Fourier transform, inverse fast fourier transform) behaviour
Make, and IFFT operation is executed to ofdm signal and may result in the interference-for having larger PAR substantially as coloured noise.And
Coloured noise compares the further decline that will lead to power system capacity with random noise.
