Conventional fixed spectrum allocation results in a large part of frequency band remaining underutilized. Channels that are dedicated to licensed (primary) users are out of reach of unlicensed users, while the licensed users do not occupy the channel completely, at all times. 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.
