Apparatus and method for removing an interference signal using selective frequency phase converter

摘要

The present invention relates to an interference cancellation apparatus and method using the optional frequency-phase converter. Interference cancellation apparatus using a frequency selective phase converter according to the present invention, the phase conversion of the received RF signal to a phase difference of 180 degrees from each other I the first phase converter to the differential output to the first signal and the second signal; Receiving the first signal a second phase converter for selectively converting the phase of the signal in a particular frequency band; Receiving the second signal converter for selectively converting the third phase the phase of the signal in a particular frequency band; A timing controller for correcting the signal delay time between the second phase of the converter output and the third output of the phase converter; And said selectively phase-shifted frequency is, the delay time includes an adder that adds the correction signal is two, the second and the third phase is the phase of the transducer signal in a particular frequency band of claim 1 to prevent possible 180 degree phase difference between each other and a second signal respectively, characterized in that the phase conversion to.
