Cognitive Radio Spectrum Sharing for Device to Device (D2D) Communication in Cellular Network
This paper addresses the Spectrum sharing technique for Device to Device (D2D) communication which provides efficient communication by allowing the under utilized spectrum to be shared by other devices and interference management among D2D users. Spectrum sharing is a technique which involves simultaneous usage of a specific radio frequency band by a number of independent users for different applications or using different technologies. This paper first outlines the different challenges in implementing Spectrum sharing for D2D communication. Next there is a qualitative overview of the existing spectrum sharing and interference management techniques for cellular networks. The demonstration for device synchronization and data transfer takes between the devices is depicted. Also cognition along with limited information exchange between D2D users will be used to reduce interference and increase spectral efficiency of D2D users. Simulation results are provided to verify the analytical results. This proposed technique is implemented using LABVIEW 2013.
