Abstract:

To improve the performance of resource management of the cognitive radio networks, a new wide-band common coordinate channel (CCC) with lower transmitting power and better anti-jamming ability is presented. Instantaneous and reliable sensing information exchange is carried out through this channel. According to interference temperature, the interference between the CCC and the primary user is analyzed in urban areas.Then the relations of the jamming probability and the other parameters are gotten. Analysis and simulation results show that for the common narrow band system, the lower jamming probability can be obtained with this scheme.
