Energy-efficient power allocation in analogue network coding based multi-hop D2D communication
Proceedings of the Conference on Research in Adaptive and Convergent Systems, 2019Energy-efficiency (EE) is critical for device-to-device (D2D) communication due to limited battery capacity. However, most of the studies on D2D communication based on network coding focus on improving network throughput, and less on the coding and decoding energy consumption caused by network coding.

Multicast is a promising technique for mobile network operators to efficiently launch media services. With its standardization in LTE networks, LTE multicast has attracted growing attention from industry recently. In this paper, we investigate the energy-efficient resource allocation for multicast services in orthogonal frequency division multiple ...

IEEE Communications Letters, 2012
In this letter, we consider a two-way relay channel (TWRC) with two end nodes and k relay nodes, where end nodes have the full channel-state information (CSI) and relay nodes only have the channel-amplitude information (CAI). With the objective of minimizing transmit power consumption at required end-to-end rates, energy-efficient relay selection (RS ...

In this work we evaluate the energy efficiency (EE) of some recently proposed network-coded cooperative (NCC) schemes based on orthogonal frequency division multiple access (OFDMA) in an underwater acoustic network (UWAN) subjected to Generalized K fading. Our analysis also encompasses the frequency-dependent attenuation typical of the UWA channel, and

Dynamic energy allocation of commondity Wi-Fi signals using programmable coding metasurface
2019 International Applied Computational Electromagnetics Society Symposium - China (ACES), 2019In this work, we present the first experimental result of dynamic energy allocation of commodity Wi-Fi signals. To that end, a programmable phase-binary coding metasurface, working at 2.45GHz, has been designed, and an efficient optimization algorithm of online adjusting the spatial intensity distribution of Wi-Fi signals has been developed.

In this paper, we focus on studying the optimal joint relay positioning and power allocation for two serial relays' transmission. We consider that information exchanges in Rayleigh flat-fading channels between two end-users which have symmetric traffic requirements in terms of the data rate.

AbstractModern 5G heterogeneous networks (HetNets) require hybrid multiple access technology for optimal performance. The feasibility of a hybrid power domain sparse code nonorthogonal multiple access (PD‐SCMA) that integrates both power domain nonorthogonal multiple access (PD‐NOMA) and sparse code multiple access (SCMA) for an uplink hierarchical ...

This paper investigates the outage behavior and power allocation problem in a two-user network-coded cooperative cognitive radio network over Rayleigh fading channels. First, we derive an exact expression for the outage probability of the secondary transmissions, and then we propose an approximate expression whose validity limits are later evaluated ...

The multiple access broadcast (MABC) is an effective two phases transmission (2P) ANC protocol for the half-duplex (HD) communication mode. However, MABC does not make use of channel gain of the direct link (DL) no matter how strong it is. On the other hand, the time division broadcast (TDBC) is known as a three phases transmission (3P) protocol which ...
