A method for obtaining a self-interference channel response of the channel and full-duplex communication

The present invention is applicable to the field of communication technology, there is provided an interference channel obtained from the channel response and the method for full-duplex communication, the method comprising: using a plurality of first reference signals for channel estimation of the channel from interference, obtained from interference channel channel response estimation value, time interval between adjacent reference signal interval is less than the self-interference coherence time of the channel, adjacent to the reference frequency-domain interval between signals is smaller than the self-interference coherence bandwidth of the channel, determining an estimated value is then responds according to the channel each channel frequency stabilization zone domain response, and randomly selected frequencies or select a channel in response to greater frequency as the transmission frequency point reference signal in the frequency within a stable range-domain response in each channel, in response to the hair in the acquired channel after the relationship between the frequency point and a non-transmission frequency point, to obtain a channel in all time domain and frequency domain based on the received direction signal in response to the reference signal corresponding to the frequency point. The present invention saves resources for the reference signal from the interfering channel estimation.
