PROBLEM TO BE SOLVED: To retrieve a plurality of base stations without missing. SOLUTION: A reception buffer 12 sequentially stores received data from a plurality of base stations. When a unique word(UW) detection circuit 14 detects a unique word from the received data, a storage address of the reception buffer 12 at a point of time of the detection is stored together with a received signal strength indicator RSSI level denoting the reception level at the detection of the unique word stored in an address/RSSI buffer 16. A CPU 22 reads an address stored in the address/RSSI buffer 16 after the lapse of a prescribed time, reads received data stored in the reception buffer 12 after the read address by generating a read address from an address generating circuit 20, a descrambler DSC circuit 18 applies descrambling processing to the received data and a cyclic redundancy check(CRC) circuit 19 makes error detection using a CRC bit to read the received data. |
