This invention relates to the field of communication technology, and particularly to a communication exchange mechanism design based on frequency hopping, which is applicable to cognitive radio networks. A method for generating hopping frequency sequences for multi-transceiver cognitive radio networks is provided, so as to realize the optimization and tradeoff of the five performance parameters, i.e. DoR, MTTR, ATTR, CL, and NSS. That, is, for a given DoR, the frequency-hopping system should minimize the NSS of the clock synchronous and asynchronous frequency-hopping systems under the condition of MTTR=ATTR=1 and CL
