Abstract:
1. A radio receiving apparatus comprising: a despreading section that provides despreading processing to received signals to extract in-phase components and quadrature components of received signals of predetermined paths; a RAKE combining section that combines the in-phase components and quadrature components of the despread received signals of predetermined paths; a complex correlation processing section that provides complex correlation processing to the in-phase components and quadrature components of the despread received signals of predetermined paths; a path combining section that combines the despread received signals of predetermined paths subjected to the complex correlation processing per in-phase component and quadrature component to generate in-phase components and quadrature components of combined signals; and a phase rotation calculating section that calculates a phase rotation amount in the received signals using the generated in-phase components and quadrature components of the combined signals.
