The present invention relates to a mixed mode signal environment-based frequency rearrangement system which, when a radio repeater forming a radio link between a base station and a terminal processes a mixed mode signal having a WCDMA signal and an LTE signal mixed therein, enables the radio repeater to efficiently processes the mixed mode signal and flexibly improves a software-wise frequency rearrangement configuration. The radio repeater of the system comprises: an ADC for converting an analog signal to a digital signal; an FPGA for dividing the types of digital signals converted by the ADC into WCDMA, LTE, GSM, and CDMA, calculating a ratio depending on the type of each signal with respect to overall signals, rearranging the frequency to the case, which is close to the computed ratio, among multiple cases for frequency rearrangement, and generating a synchronization signal for distinguishing the transmission and reception timing of a wireless communication link; and a DAC for converting the digital signal, output from the FPGA, to an analog signal. |
