PROBLEM TO BE SOLVED: To provide a radio system that improves data transmission efficiency and is capable of identifying an error factor when a synchronization error occurs.;SOLUTION: In a radio base station 1, an O/E 13b in an optical module 13 inversely and photoelectrically converts a light signal from an optical fiber 100b, and serial-parallel converter 12b of a serial-parallel/parallel-serial converter 12 parallels a signal electrically converted by the O/E 13b. A baseband signal processor 11 processes data paralleled by the serial-parallel converter 12b. At this point, an LOS detection level variable element 14b in an optical detection correction circuit 14 varies a detection level in an LOS signal 101 by an external resistor, or the like according to the asserted LOS signal 101, when an incoming line is disconnected or a level in the optical reception signal is decreased, and the control of a controller 14a.;COPYRIGHT: (C)2006,JPO&NCIPI
