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. If the spread spectrum signal, of which the correlation values with the diffusion codes are at least at the predetermined, level, can not be detected within the predetermined detection phase range, the detection phase range is widened based on the reference phase position.
