Cooperative relaying in cellular networks for improving receiver diversity and cell radius
… the foremost requirement. With the inception of cooperative relaying technology, a novel wireless relaying method of sharing the terminal node capabilities to forward the signal created a new paradigm to greatly improve the quality of the services and soon became the significant research area in …

Terahertz Band Communications: System Architecture and Physical Layer Solutions
… the problem of beam blockage and present a novel cooperative relaying system to extend transmission range as well as improve signal reception quality. Finally, for multimedia applications of THz-band communications (e.g. 3-D virtual reality content) we present a data embedding scheme that can …

Communications over fading channels with partial channel information : performance and design criteria
… are examined for amplify-and-forward cooperative relaying schemes in Rayleigh fading channels. Simple power allocation strategies are determined by using knowledge of the mean strengths of the channels. Suboptimal algorithms are proposed for cases that optimal receivers are difficult …

Cooperative DVB-H: Raptor-Network Coding Protocols for Reliable and Energy Efficient Multimedia Communications
… problem. In this thesis, we focus on a cooperative extension to the Digital Video Broadcasting – Handheld (DVB-H) standard, forming a cooperative broadcast network whereby terminal-to-terminal cooperation creates a distributed form of multi-input-multi-output (MIMO) that supplements …

Performance analysis of cooperative relay networks in presence of interference
In the past decade, cooperative communication has emerged as an attractive technique for overcoming the shortcomings of point-to-point wireless communications systems. Cooperative relaying improves the performance of wireless networks by forming an array of multiple independent virtual sources …

Cooperation in Wireless Networks
… antennas on the same node, the so-called cooperative communications (CC) has been introduced. Under CC, each node is equipped with only a single antenna and spatial diversity is achieved by exploiting the antennas on other nodes in the network through cooperative relaying. The goal of this …
