PROBLEM TO BE SOLVED: To provide an FH system radio communication module and equipment/ method for radio communication which enable increase in a data communication speed. SOLUTION: In order to transmit and receive data by multi-channels, a plurality of modulation parts 20, 30 and demodulation parts 32 and 50 are provided and a counter 18 for counting the errors of data received by each of the parts 20 and 30 is provided. The counter counts the errors from each of the parts 20 and 30 and when it reaches a prescribed count, the counter stops using the part 30 and the part 50 except for a basic channel. When the error count of the part 32 of the basic channel is smaller than the prescribed count within a prescribed time in this state, using of the part 30 and the part 50 is restarted. Also when there are more modulation part and demodulation part, a channel to be used is increased or reduced automatically depending on an error rate in the same way as the above. |
