Device-to-device (D2D) communication, which enables two closely located users to communicate with each other without traversing the base station (BS), has become an emerging technology for network engineers to optimize network performance. This paper presents a framework based on stochastic geometry for D2D multichannel overlaying uplink cellular networks. In this framework, a part of mobile devices...
Sparse code multiple access (SCMA) is a new modulation and non-orthogonal multiple access scheme for 5G systems, in which the coded bits are mapped to multidimensional sparse codewords, and the message passing algorithm (MPA) is employed to detect multi-user signals. Device-to-Device communications underlaying cellular network is also a key technique in 5G networks; hence the sparse codes allocation...
In this article we investigate energy efficient power control in the context of D2D (Device to Device) communications. An approach based on game theory is used to implement a fully distributed power control scheme. We propose a practical implementation of a low complexity power allocation algorithm that we compare with an existing NLP (Non Linear Programming) power allocation algorithm. Simulations...
In this paper we propose an optimal resource management scheme for device-to-device (D2D) communications utilising uplink resources in a Single Carrier Frequency Division Multiple Access (SC-FDMA) system, which is the uplink access scheme in the 3GPP-Long Term Evolution (LTE) standard. We consider an arbitrary number of conventional cellular (CC) User Equipments (UEs) and D2D UEs, both utilising the...
