Title:
RECEIVING METHOD AND RECEIVER
Document Type and Number:
Japanese Patent JP3952335
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To detect delay timing of a delay signal received through plural propagation paths in a short time and to accurately demodulate it.
SOLUTION: This receiver respectively detects delay timings by checking the phases of plural delay signals at the time of starting receiving, also respectively detects the phases of plural delay signals by performing inverse diffusion with a diffusion code of phases that respectively correspond to the delay timings to demodulate and checking the phases of plural delay signals within the prescribed detection range with the delay timing of a delay signal that first arrives among delay signals detected the last time as reference after receiving start time and also expands a detection range to a prescribed range with the delay timing of the delay signal that first arrives among the delay signals detected the last time as reference when plural delay signals are demodulated by the diffusion code of the phases that respectively correspond to the delay timings and the delay timings can no longer be detected within the detection range.
