Abstract
Herein disclosed are a radio receiving apparatus and a receiving system switching control method used in the radio receiving apparatus. The radio receiving apparatus has an active receiving system and a standby receiving system including respective equalizers, and a changeover switch for performing a switching between the active receiving system and the standby receiving system. The radio receiving apparatus further includes an alarm predicting information predicting means for detecting alarm predicting information in each of the equalizers and a switching control means for controlling a switching condition of the changeover switch on the basis of the alarm predicting information detected by the alarm predicting information detecting means, where the alarm predicting information as internal information of the equalizers is monitored to predict a malfunction of a receiving circuit to switch the circuit before the circuit is hit. It is therefore possible to reduce a hit rate of the circuit.
