Abstract
A method of operating a repeater comprises selecting some of adaptive filter coefficients among a plurality of adaptive filter coefficients of an adaptive filter used for interference cancellation, based on the size of a coefficient, generating a predicted interference signal using the selected adaptive filter coefficients and generating an interference-canceled communication signal from a received signal using the generated predicted interference signal.
Claims15
A method of operating a repeater, the method comprising:
- generating a plurality of adaptive filter coefficients of an adaptive filter based on a received signal;
- selecting, from the generated plurality of adaptive filter coefficients, some of adaptive filter coefficients for interference cancellation, based on a size of a coefficient;
- generating a predicted interference signal using the selected adaptive filter coefficients;
- and
- generating an interference-canceled communication signal from a received signal using the generated predicted interference signal.
A repeater comprising:
- a controller configured to:
- generate a plurality of adaptive filter coefficients of an adaptive filter based on a received signal;
- and
- select, from the generated plurality of adaptive filter coefficients, some of adaptive filter coefficients for interference cancellation, based on a size of a coefficient, and output the selected adaptive filter coefficients;
- the adaptive filter configured to generate a predicted interference signal using the selected adaptive filter coefficients;
- and
- a subtracter configured to generate an interference-canceled communication signal from a received signal using the generated predicted interference signal.
