| 摘要 |
The embodiments of the present invention provide an interference cancellation device and method, relating to the technical field of communications; the invention can eliminate a near-field reflection self-interference component. The method comprises: a radio frequency (RF) reference signal generated according to an emitted signal is obtained; an RF reception signal is obtained by means of a primary receiving antenna; according to said RF reference signal, interference cancellation is performed on the RF reception signal, and a first processing signal is generated; according to a digital baseband reference signal corresponding to said RF reference signal, and a first digital signal obtained by sampling said first processing signal, near-field reflection self-interference channel estimation is performed to obtain near-field reflection self-interference component parameters; according to said near-field reflection self-interference component parameters and said RF reference signal, the near-field reflection self-interference signal is reconstructed to obtain a near-field reflection self-interference signal; according to said near-field reflection self-interference signal, interference cancellation is performed on said first processing signal to obtain a second processing signal. The present invention is used for interference cancellation. |
