A novel resource management channel of cognitive radio
Zhao Lu-wen · Journal of Lanzhou University · 2008
In order to improve the performance of the cognitive radio resource management,a new wide-band resource management channel (WB/RMC) with lower transmitting power and better anti-jamming ability is presented.Instantaneous and reliable sensing information exchange is carried out utilizing DSSS.According to interference temperature,the interference of the WB/RMC to primary user is analyzed.Then,we get the relation between interference temperature limit of the primary user and the number of the accommodated sense users in a certain area.Analysis and simulation results show that this scheme can avoid the interference between sense users and primary user.Moreover,this scheme can provide enough chances for sense users to access the WB/RMC.
