With the exponential increase in the use of high powered wireless devices, there is a demand to utilize the spectrum efficiently, intelligently and optimally. Cognitive Radio is an attractive concept and solution, capable of addressing this issue. This paper investigates a statistical simulation model for spectrum sensing of cognitive radio and the associated interference probability calculation methodologies. The capability to simulate multiple cognitive radio systems with issues of complex range of spectrum engineering and radio compatibility are explored. The results show that the model was able to simulate mutual positioning of the systems under consideration with spatial and temporal distributions of the signals taken into account. The model has restrictions to simulate CDMA/OFDMA modules as victim. Research on simulation models of dynamic spectrum management has the capability to shape the communication protocols and technologies of future.
