ABSTRACT:
The spread spectrum reception apparatus is provided with a RAKE-combination path timing detector which detects a first path using a delay profile produced with a correlation electric power value with improved signal-to-electric power ration by performing cyclic integration of electric power, detects a second path based on the corrected delay profile by correcting a correlation electric power value of the delay profile using a correction coefficient corresponding to a deviation of delay time of the first path signal. A correction coefficient storing unit stores correction coefficient pre-calculated giving consideration to time correlation of interference and thermal noise.
