A transmitting device, for handling signal interference, comprises a first transmitting circuit, for processing a first plurality of baseband signals, to generate a first plurality of radio frequency signals; a second transmitting circuit, for processing a second plurality of baseband signals and a plurality of input signals, to generate a second plurality of radio frequency signals; a feedback circuit, coupled to the second transmitting circuit, for processing the second plurality of radio frequency signals and a plurality of leakage signals, to generate a plurality of error signals; and a control circuit, coupled to the first transmitting circuit, the second transmitting circuit and the feedback circuit, for generating the plurality of input signals according to the first plurality of baseband signals and the plurality of error signals.

Device and method of handling signal interference

A method of interference cancellation includes the following steps: performing a take-energy operation on a to-be-sent signal at multiple times to generate multiple to-be-sent signal powers; performing a first high-pass operation on the to-be-sent signal powers to generate a to-be-sent high-pass result; performing a second high-pass operation on a received signal to generate a received high-pass result; adjusting multiple filter coefficients according to the to-be-sent high-pass result and the received high-pass result; and generating a recover signal according to the filter coefficients.
