Abstract:
|
The development of the Dynamic Spectrum Access/Cogni- tive Radio (DSA/CR) technology can signi cantly bene t from the availability of realistic models able to accurately
capture and reproduce the statistical properties of spectrum usage in real wireless communication systems. Relying on
eld measurements of real systems, this paper analyzes the joint time-frequency statistical properties of spectrum usage
and develops adequate models describing the observed char- acteristics. Based on such models, a sophisticated method is also proposed to generate arti cial spectrum data for simulation or other purposes. The proposed method is able to accurately reproduce the statistical time-frequency characteristics of spectrum usage in real systems. |
