DIVERSITY-TYPE RECEIVER, RECEPTION METHOD AND RECEPTION PROGRAM USING THE DIVERSITY-TYPE RECEIVER, AND RECORDING MEDIUM STORED WITH THE RECEPTION PROGRAM USING DIVERSITY TYPE RECEIVER

摘要

PROBLEM TO BE SOLVED: To carry out diversity combining without being affected by the Doppler effect at high speed movement in particular by decreasing characteristics deterioration due to inter-carrier interference (ICI) under a multipath environment. SOLUTION: A diversity-type receiver is configured so as to be capable of selecting a complex signal from an antenna means with directivity, on the basis of information such as a vehicle speed in order to solve above problem. Thus, the receiver uses only a complex signal acquired from an antenna means with a particular directivity characteristic in the case of the occurrence of characteristic deterioration due to the inter-carrier interference, and the receiver can apply diversity combining to complex signals obtained from all the antenna means, when the inter-carrier interference is comparatively few.
