<P>PROBLEM TO BE SOLVED: To analyze a communication signal having different information in every band where the entire frequency band is divided into a plurality of bands, wherein information of one band is included in the other band. <P>SOLUTION: This method for analyzing a communication signal includes a shifting process for shifting a communication signal including a UL (uplink) signal and a DL (downlink) signal with the UL information included and going by a UL center frequency in the direction from the DL signal to the UL signal for as much as a preset shift frequency Δf (step S6 and S7), a demodulating and decoding process for applying demodulation and decoding processing to the DL signal included in the communication signal shifted in the shifting process (step S8), an information acquiring process for acquiring information from an analysis result of the DL signal subjected to the demodulating and decoding process (step S9), and an analyzing process for analyzing the UL signal on the basis of the UL information acquired in the information acquiring process (step S11). <P>COPYRIGHT: (C)2007,JPO&INPIT |
