Compressive Neighbor Discovery in Cellular Networks

S consumption. In [3][4], a compressive neighbor discovery technique was Device-to-device (D2D) communication has received more and more attentions recently. Although its traditional proposed, and significant gains were reported over existing application was mainly in networks without pre-existing random access discovery solutions, such as the birthday infrastructure like Ad Hoc, nowadays D2D is experiencing a protocol [5]. [3] and [4] introduce the basic concept and rapid growth in infrastructure networks like cellular networks, general principle of compressive neighbor discovery, which as a means to allow terminals of infrastructure networks to can be used in different systems. In this paper, we focus on the directly communicate and coordinate with each other. It has the detailed designing issues of compressive neighbor discovery in potential to become an important enhancement and cellular systems. In particular, we will discuss the design of complement to centralized communication in cellular networks. neighbor discovery period under the constraint of the frame D2D communication in cellular systems exploits the high- structure, a codebook-based signature allocation technique (to quality channel links between neighboring terminals to bring assign ID-specific signatures to terminals), and the signature benefits like performance improvement and/or functionality codebook design. Our first priority is to minimize the impact of enhancement. Typical applications include data sharing and D2D on the current cellular systems and simplify the data forwarding.
