A uniform mobile user quality of service and a distributed use of the spectrum represent the
key-ingredients for next generation cellular networks. Toward this end, physical layer …

BACKGROUND In wireless cellular networks, the deployment offixed relay stations has
been considered as an alternative for improving not only cell coverage but also transmission …

Wireless networks with linear topology, where nodes generate their own traffic and relay
other nodes' traffic, have attracted increasing attention. Indeed, they well represent sensor …

Cooperative communication is a recent paradigm for wireless relay networks wherein
multiple wireless terminals share their resources to jointly transmit information of which they …

The concept of cooperation in wireless communication networks has drawn significant
attention recently from both academia and industry as it can be effective in addressing the …

In this correspondence, we advocate the exploitation of direct links for downlink cooperative
cellular networks, where one base station (source) communicates with one out of N mobile …

Emerging cellular networks are likely to handle users with heterogeneous quality of service
requirements attending to the nature of their underlying service application, the quality of …

An ever-growing demand for higher data-rates has facilitated the growth of wireless
networks in the past decades. These networks, however, are known to exhibit capacity and …

Wireless relays extend coverage, improve spectral efficiency, and enhance reliability and
rates of wireless cellular communication systems. In this work, we introduce the fundamental …

Next-generation wireless networks will go beyond the pointto-point or point-to-multipoint
paradigms of classical cellular networks. They will be based on complex interactions, where …
