<p>In a spectrum spread receiving apparatus, frequency converting parts (201-1,201-2) convert two radio signals, which have been spectrum-spread modulated in accordance with spread codes and have their respective different carrier frequencies, into intermediate frequency signals having substantially the same intermediate frequency, and then output those intermediate frequency signals. An adder (102) adds together the two intermediate frequency signals from the frequency converting parts (201-1,201-2) to output a resultant combined intermediate frequency signal, which is then supplied, via an analog signal processing part (103) and an A/D converter (117), to a reception processing part (104). The reception processing part (104) uses the spread codes to despread, based on the digital signals from the A/D converter (117), the digital signals included in the two radio signals, thereby demodulating them to the digital data for output.</p> |
