Abstract: In the field of communication spectrum requirement is the biggest issue. Spectrum sharing is a technique in which sharing the licensed spectrum for the Heterogeneous network like wireless in the dynamic manner will be implemented. In this, we can sense and analyze the bands which are unoccupied, allocated bands and free bands by calculating a metric of free spectrum. If spectrum is free then spectrum sharing technique assigns available channel to new user without harming existing primary users. Hence it provides the opportunistic access to the licensed spectrum for the unlicensed users and they try to access the spectrum available without causing any interference to the primary users. To design these types of schemes managing the interference is the major component.
