  • Patent number: 6421369
    Abstract: In a receiving method and receiver for spread spectrum signals, a predetermined detection phase range is set as a reference phase position with a receiving timing of a spectrum signal having the highest correlation value with a diffusion code among a plurality of spread spectrum signals received, spread spectrum signals of which the correlation values with the diffusion codes are a predetermined level or more are detected from the spread spectrum signals within the predetermined detection phase range, a demodulation signal is generated from the spread spectrum signals, of which the correlation values are at least at the predetermined level. Then, the steps of setting the predetermined detection phase range, detecting the spread spectrum signals, and generating the modulation signal are repeated.
