RF RELAY OF FULL-DUPLEX AND METHOD FOR REDUCING INTERFERENCE OF EM-LEVEL THEREOF

摘要

PURPOSE: A full duplex mode wireless repeater and an EM(Electromagnetic wave)-level interference eliminating method are provided to prevent receipt of an interference signal of a transmission antenna. CONSTITUTION: A receiving antenna(310) receives a radio frequency signal. The receipt processor(320) down-converts the radio frequency signal into an intermediate frequency signal. An ADC(330) converts the intermediate frequency signal into a digital intermediate frequency signal. A signal transducer(340) includes a channel estimating part(342), a matrix generating part(344) and an interference eliminating part(346). A DAC(350) converts the digital intermediate frequency into an analog intermediate frequency signal. A transmission processor(360) up-converts the analog intermediate frequency signal to a radio frequency signal. A transmission antenna(370) transmits the converted radio frequency signal.
