Abstract
Complex correlation sectioncomplex-multiplies baseband signals obtained by frequency-converting known signals sent from base station apparatuses, which are candidate communication partners, to baseband frequencies by known patterns to distinguish signals of the respective base station apparatuses, despreads the baseband signals and obtains amplitude values. Desired signal power measuring sectionaverages the amplitude values with a predetermined number of symbols, interference signal power measuring sectionthat calculates a desired signal power value by suppressing the interference component separates the interference component by subtracting the desired signal power value from the amplitude values. Division sectiondivides the desired signal by the interference signal, calculates a CIR value and outputs the CIR value to transmission sections-to-n. Transmission sections-to-n carry out processing necessary for radio transmission such as modulation, coding and frequency conversion, etc. and send the signal via antenna
