Abstract
An interference cancellation repeater configured to cancel an interference signal included in an input signal, the interference cancellation repeater including: a canceller configured to generate an interference canceled signal based on the input signal and an estimated signal; a digital filter configured to filter the interference canceled signal to generate an output signal; an interference signal detector configured to generate interference signal existence interval information using the input signal and the output signal; and an adaptive filter configured to receive the interference canceled signal and the output signal, and generate the estimated signal based on the interference signal existence interval information. Information of the signal existence section.
Claims11
An interference cancellation repeater configured to cancel an interference signal included in an input signal, the interference cancellation repeater comprising at least one memory and at least one processor to implement:
- a canceller configured to generate an interference canceled signal based on the input signal and an estimated signal;
- a digital filter configured to filter the interference canceled signal to generate an output signal;
- an interference signal detector configured to generate interference signal existence interval information using the input signal and the output signal;
- and
- an adaptive filter configured to receive the interference canceled signal and the output signal, and generate the estimated signal based on the interference signal existence interval information.
An interference cancellation repeater configured to cancel an interference signal included in an input signal, the interference cancellation repeater comprising at least one memory and at least one processor to implement:
- a canceller configured to generate an interference canceled signal based on the input signal and an estimated signal;
- a digital filter configured to filter the interference canceled signal to generate an output signal;
- an interference signal detector configured to detect an interval in which the interference signal exists in the input signal based on the input signal and the output signal;
- and
- an adaptive filter configured to generate the estimated signal based on the interference canceled signal and the output signal in the detected interval.
