PROBLEM TO BE SOLVED: To conduct bit synchronizing processing with high accuracy corresponding to a state of a radio channel and a change in a communication protocol by means of the software. SOLUTION: The receiver is provided with an arithmetic means 1 that calculates an edge mean error and an edge error maximum value based on an edge detection signal, an arithmetic time value and a sampling clock signal 191 and provides an output of the result as a calculated value and with a storage means 16 that stores a permissible range of the edge mean error and a maximum value of the edge error, and also with a comparison means 15 that reads the permissible range of the edge mean error and the maximum value of the edge error, compares them with the calculated values and provides an output of an error signal when the comparison indicates the calculated values to be at the outside of the specified range and provides an output of a synchronization establishment signal when the comparison indicates the calculated values to be at within the specified range. Thus, bit synchronization processing with high accuracy is conducted by the software processing. |
