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.

Abstract: PURPOSE: A non-oscillation wireless repeating apparatus and a method thereof are provided to repeat a high output and high purity radio signal by increasing isolation between transmission and reception of a repeating base station. CONSTITUTION: A radio signal transmitted from a doner base station, a near interfering signal of a transmission antenna of a repeater, and an indirect interfering signal are received(S100). The interfering signal is extracted and a phase of the interfering signal is delayed as much as 1/4 to generate a orthogonal subtraction signal(S200). A feedback gain of a radio signal with a modulated amplitude is detected(S300). The radio signal and the orthogonal subtraction signal are received and combined, and the interfering signal is removed(S400). The amplitude of the radio signal is modulated to a certain size in order to measure a correlation degree(S500). A generated noise signal is removed(S600). A received signal is amplified(S700). The amplified signal is radiated in a free space(S800).
