In this paper, together with its Part II, the impact of relaying and adaptive modulation and coding (AMC) on data throughput in narrowband wireless multi-hop networks is investigated. This part focuses on the physical layer of a single-carrier narrowband time division multiple access (TDMA) transmission in the very high frequency (VHF) band. The transmission chain is designed for a narrowband, ...

Network coding, where relay nodes combine the information received from multiple links rather than simply replicating and forwarding the received packets, has shown the promise of significantly improving system performance. In very recent works, multiple researchers have presented methods for increasing system throughput by employing network coding inspired methods to mix packets at the physica...

Full-duplex multi-way relaying is a potential solution for supporting high data rates in future Internet-of-Things (IoT) and 5G networks. Thus, in this paper the full-duplex MIMO multi-way channel consisting of 3 users (Y-channel) with M antennas each and a common relay node with N antennas is studied. Each user wants to exchange messages with all the other users via the relay. A transmission s...

A Wireless Network Coding (WNC) a.k.a. a Physical Layer Network Coding in multi-source multi-node scenarios has shown its potential to increase network throughput compared to a communication based on an orthogonal separation of individual transmissions. In this paper we analyse necessary steps that have to be done to initialize the WNC communication including mainly establishing of relay operat...

This paper proposes a principled extension of the traditional single-layer flat sparse coding scheme, where a two-layer coding scheme is derived based on theoretical analysis of nonlinear functional approximation that extends recent results for local coordinate coding. The two-layer approach can be easily generalized to deeper structures in a hierarchical multiple-layer manner. Empirically, it ...

To quantify human visual system characteristics to carry out rate controlling efficiently, this paper presents a new macroblock (MB) layer rate control algorithm for multi-view video coding (MVC) by improving quadratic rate-quantitative (R-Q) model based on the just noticeable distortion (JND) model. Firstly, the pixel-JND value of color image in multi-view video is stroked according to the rel...

Network coding refers to a scheme where a node is allowed to generate output data by mixing (i.e., computing certain functions of) its received data. The unique characteristics of wireless medium renders network coding particularly useful. For instance, network coding can be used to achieve the minimum energy-per-bit for multicasting in a wireless ad hoc network. In addition to optimizing energ...
