The use of Cognitive Radio Network (CRN) for spectrum utilization is very beneficial to address scarcity of frequency spectrum. It can solve the problem of spectrum scarcity. The one of the areas of concern in spectrum sensing is the amount of energy that is consumed in spectrum sensing performed by unlicensed/secondary users. There are many frame structures which are being used for spectrum sensing and they are very capable of performing spectrum efficient and energy efficient spectrum sensing individually, but it does not fulfill the need of modern era where the authors need a combined spectrum and energy efficient spectrum sensing technique.
