Abstract
A reference pattern comparing means 14 detects the number of error bits, using a reference pattern data portion embedded in the received signal. An error correcting means 15 detects the number of the corrected bits in the user data portion in the signal. The bit error rate measuring means 16 measures the bit error rate, on the basis of the number of the error bits and the corrected bits. The electric field level measuring means 17 measures the level of the electric field of the received signal. The electric field correcting means 18 corrects the level of the electric field, on the basis of the bit error rate. The control of the handing over of the radio communication channel is carried out, on the basis of the corrected electric field.
