<p>PROBLEM TO BE SOLVED: To provide a CDMA transmitting-receiving circuit which is capable of coping with a frequency band shift in CDMA modulation signals and of decreasing a transmit/receive processing load of CDMA modulation signals. SOLUTION: A set timing management part 13, which monitors the timing of a frame and switches symbol timing and diffusion codes when a frequency band is shifted, is provided, by which the transmit/receive processing load of CDMA modulation signals can be reduced.</p> |
