A receiver operated using a spread spectrum code division multiple access mode includes integrators for respectively integrating two signals of an in-phase channel and a quadrature channel, a comparator for comparing the two integrated signals, and a multiplexer for selectively outputting a signal having the greater magnitude between the two signals of the in-phase and quadrature channels in accordance with the result of the comparison in the comparator. Therefore, one channel outputting a signal having the greater magnitude between the two signals is selected to despread and demodulate the signal, using the regular difference of the outputs from the in-phase and quadrature channels. Thus, the favorable channel conditions can be maintained, and the despreading and demodulating can be simplified.
