Abstract
A diversity receiver carries out error detection, error correction, and data detection on each detected data stringAn output switching unitoutputs a decoded data stringof a branch selected by a branch selectorThe branch selectorselects a branch of highest priority in priority informationfrom branches of which a data detection signalindicates that the data is valid and of which the number of error symbolscoincides with a minimum value. In the priority informationhigher priority is assigned to a branch that includes an antenna of which the coverage is closer to that of an antenna included in a branch selected at the immediately-previous time. Thus, selected from the plurality of branches having the minimum number of error symbolsis the one that includes the antenna of which the coverage is closest to the coverage of the antenna included in the branch selected at the immediately-previous time. Therefore, it is possible to suppress the occurrence of misselection of a poor-quality branch, and improve a reception characteristic.
