摘要： A first conversion unit (201) converts a signal from a time domain to a frequency domain. A signal extraction unit (202) extracts common channel information included in the signal which has been converted by the first conversion unit (201). A signal substitution unit (207) restores the common channel information which has been extracted by the signal extraction unit (202). An addition unit (208) substitutes the common channel information which has been restored by the signal substitution unit (207) for the common channel information included in the signal which has been converted by the first conversion unit (201). A second conversion unit (209) converts the signal including the common channel information substituted, which has been converted by the first conversion unit (201), from the frequency domain to the time domain.

摘要： Provided is a communication capacity evaluating apparatus whereby the communication capacity can be grasped and the necessity of changing the content of a dead spot measure after the placement of a relay apparatus can be eliminated. In the communication capacity evaluating apparatus, a system information analyzing unit (121) acquires, from a received signal, used-band information of the communication using a MIMO mode. An S/N calculating unit (122) analyzes the received signal to determine a signal-to-noise ratio. A channel estimating unit (123) analyzes the received signal to determine a channel matrix. A throughput limit calculating unit (124) calculates the limit value of the communication capacity on the basis of the used-band information, information about the number of transmission antennas of a base station (180), information about the number of reception antennas of a radio relay apparatus (100) stored in advance, the signal-to-noise ratio and the channel matrix. A display unit (133) displays the result of a comparison between the limit value and a desired value of communication capacity set in advance.
