RADIO COMMUNICATION EQUIPMENT AND RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio communication equipment that conducts communication with a communication system corresponding to a change in channel. SOLUTION: A separate section 109 separates an output signal from a demodulation section 108 into received data and an OK signal or an NG signal, provides an output of the received data and an output of the OK signal or the NG signal to a transmission system changeover decision section 110. The transmission system changeover decision section 110 stores the number of times of receiving the OK signal or the NG signal, decides whether or not revising a transmission system depending on the frequency of reception of the OK signal or the NG signal and outputs an instruction as to whether or not the transmission system is to be revised to a transmission system changeover control section 111. The transmission system changeover control section 111 controls a transmission frame generating section 102, a modulation section 103, a transmission wireless section 104 and an antenna multicoupler section 105 to instruct a buffer 101 to output transmission data for re-transmission when the revision of the transmission system is required according to the instruction from the transmission system changeover discrimination section 110.
