摘要

PPROBLEM TO BE SOLVED: To provide an in-phase combining space diversity reception apparatus in which reception characteristics can be improved even when there is variation in transmission line length difference between a main path and a phase difference detection path in a first reception signal side substrate and a second reception signal side substrate. PSOLUTION: The in-phase combining space diversity receiving apparatus 302 includes: a main path (MP1, MP2) for combining a first reception signal S1 and another second reception signal S2 received by space diversity; a phase difference detection path (PP1, PP2) for detecting an inter-signal phase difference between the first reception signal S1 and the second reception signal S2; a signal phase control means for controlling at least one of the phases of the first reception signal and the second reception signal S2 so as to reduce the inter-signal phase difference detected by the phase difference detection path (PP1, PP2); and a relative phase adjustment means 101 for reducing a relative phase difference that is a difference between an inter-path phase difference between the main path MP1 and the phase difference detection path PP1 and an inter-path phase difference between the main path MP2 and the phase difference detection path PP2.
