RADIO RECEIVER

摘要

A despreader 106 (107) provides despread processing to baseband signals based on timing from a searcher 105 to obtain a baseband signal of path 1 (path 2). A complex correlation section 115 (116) provides complex correlation processing to the baseband signals from the despreader 106(107) (baseband signals, which are not yet multiplied by an inverse characteristic of a channel estimation value from a channel estimating section 108). A path combining section 117 combines the signals subjected to complex correlation processing by the complex correlation sections 115 and 116. A phase estimating section 118 estimates a phase rotation amount caused by a frequency offset using the signal combined by the path combining section 117.
