PROBLEM TO BE SOLVED: To provide a receiving method capable of improving noise resistivity in a spread spectrum receiver. SOLUTION: The received outputs of n pieces of antennas arranged at almost λ/2 interval are switched and outputted in one chip period of a spread code by an antenna switch 11, and outputted as an IF signal from a high frequency amplifying part 12 and a frequency converting part 13. A PN system code correlating part 20 compensates the phase of the signal received by each antenna based on a reference signal, and operates inverse spread processing so that it is possible to demodulate SS communication radio waves with spread spectrum. |
