Cognitive radio is mainly good for spectrum sensing , sharing , allocation etc . It has wide range of application. the areas can be - cooperative spectrum sensing , security based sensing using CR,Maximum energy efficiency by using CR sensing .
sensing is mainly done to find how we can maximize the probability of detection and reduce probability of false alarming etc.
try this area ..its a good choice..
