Abstract
Abstract
The shadow effect and multi-path can be partly eliminated by the cooperative spectrum sensing. At present research on cognitive use based on cooperative spectrum sensing is in static state, the cognitive user mobility is affected by the cooperative spectrum sensing performance. The mobility of the cognitive user is considered in this paper and a dynamic cooperative spectrum sensing model is put forward based on the centralized spectrum sensing. It shows that PU is static and other cognitive user travelling in a straight line at varying velocity in the model. From the simulation results it is observed that dynamic cognitive user cannot cooperative with the static cognitive user spectrum sensing by fusion rule.
