A selector that selects an orthogonally detected output signal of I channel and an orthogonally detected output signal of Q channel and that outputs the selected signals to a path for obtaining a demodulated output signal of I channel is provided. In addition, a selector that selects an orthogonally detected output signal of Q channel and an orthogonally detected output signal of I channel and that outputs the selected signals to a path for obtaining a demodulated output signal of Q channel is provided. These selectors are switched corresponding to whether or not a PN code of I channel is the same as a PN code of Q channel. An output signal of the selector of the path for obtaining the demodulated output signal of I channel and the PN code of Q channel PNQ are ex-ORed and output as a de-spread output signal of I channel. An output signal of the selector of the path for obtaining the demodulated output signal of Q channel and the PN code PNI of I channel are ex-ORed and output as a de-spread output signal of Q channel. <IMAGE> |
