Abstract—Starting with the evolution of cellular communications in the early ’80s, the demand for two-way mobile communication services has increased tremendously. Hence, spectrum scarcity is of severe concern, which obstructs the deployment of new advanced communication services. One solution to this problem is to develop opportunistic channel access, namely, spectrum sensing using a cognitive radio. Spectrum sensing is a process of monitoring the channel in a given (available) bandwidth. Spectrum sensing approaches can be blind or non-blind. Inthispaper,various available approaches to blind spectrum sensing, are discussed. Further, a comparative study between eigenvalue based spectrum sensing approaches are illustrated.
