Abstract: An apparatus and a method for blocking transmission/reception over-input in a mobile communication repeater are provided to provide a stable service to a mobile terminal which normally performs call communication through a different frequency channel without interruption and degradation of speech quality. A reception antenna(100) receives a signal to be relayed from a base station(mobile station) of a shadow area. A BPF(Band Pass Filter)(110) filters the signal received through the reception antenna(100). An LNA(Low Noise Amplifier)(120) receives the filtered signal and amplifies it. A down-converter(130) receives the amplified signal and down-converts it into an IF(Intermediate Frequency) band. An input monitoring unit(140) measures input signal levels of each frequency channel and transmits the results. A controller(150) compares input signal level values of each frequency channel with a pre-set level value, and if an input signal level is determined as an abnormally high input for more than a certain time, the controller(150) controls such that a corresponding frequency channel is attenuated or cut off, and transfers the result. A channel filter unit(160) selectively attenuates or cuts off the entire usage band or a signal of the abnormal corresponding frequency channel. An up-converter(170) up-converts the IF signal whose entire use band or particular frequency channel was attenuated or cut off into a high frequency band. A power amplifier(180) amplifies the signal of the up-converter(170). When an abnormal over-input signal is detected, a state monitoring unit(190) reports the detection result to a corresponding base station in real time. A transmission antenna(200) transmits the signal amplified by the power amplifier(180) or the result detected by the state monitoring unit(190) to the base station.

Abstract: A radio relay apparatus having a rejection function of a periodical spurious wave and a multipath interference signal is provided to remove an interference signal generated by feedback through the same transceiving frequency, thereby transmitting a large-output signal and maximizing the efficiency of the expansion of a service area and the solution of a shadow area. A spurious wave removing unit(140) senses periodical spurious components in the signal of a frequency down-converting unit(130) and removes the periodical spurious wave components, and senses spurious wave components having periodicity out of transmitted signals, and generates and removes a reverse-phase signal having the same amplitude as that of the sensed spurious wave components. An interference signal removing unit(180) composes the same amplitude of the reverse-phase signal from an interference signal generating unit(170) and the signal received from the spurious wave removing unit and removes an interference signal.
