PROBLEM TO BE SOLVED: To provide a spread spectrum receiver in which the number of inverse spread sections is decreased so as to reduce the circuit scale. SOLUTION: The spread spectrum receiver is composed of an interleaving section 101 that interleaves received signals RxI, RxQ by an on-time clock OTCLK, an inverse spread section 102 that applies inverse spread processing to interleave signals OTI, OTQ interleaved by the interleave section 101 and supplies the resultant signals to a data latch section 104, a selector section 103 that switches PN sequence codes PnWI, PnWQ supplied to the inverse spread section 102 and supplies a selection signal Sel[n:1] to the data latch section 104, the data latch section 104 that latches the inverse spread signals DOTI, DOTQ inversely spread by the inverse spread section 102 for each selection signal Sel[n:1] supplied from the selector section 103, and n-sets of data path demodulation sections 1051-105n that demodulate the signal latched by the data latch section 104. |
