We investigate fundamental characteristics of cooperative transmission in terms of power
efficiency. By introducing the concept of “cooperative region”, we evaluate the average …

We address the drawbacks of cooperative relaying regarding its spectral inefficiency and its
channel over reservation compared to direct transmissions. We propose to exploit routing …

In this paper, we consider a dual-hop amplify-and-forward (AF) multiple-input multiple-output
(MIMO) relay system, where there is one source, one destination and K relay nodes. We …

In a relay scheme, a wireless source apparatus, a wireless destination apparatus and a
wireless relay apparatus cooperate for handling transmission failures by space/time diverse …

In this paper, Signal to noise ratio estimation in Orthogonal Frequency Division Multiplexing
based cooperative communication system is proposed. SNR estimation is needed for the …

In this paper, we consider an amplify-and-forward cooperative wireless network in which
network nodes use multiple input multiple output (MIMO) spatial division multiplexing (SDM) …

Over the last decade cooperative communication in wireless sensor networks (WSN)
received much attention. A lot of works have been done to propose a MAC layer that …

The non-orthogonal multiple access (NOMA) multiple access technique, due to its non-
orthogonality and providing access to users together, which have the same frequency and …

Over the years, the Medium Access Control (MAC) protocols for wireless networks have
considered direct-communication between source and destination. Although direct …

A generalized version of the plus-minus algorithm is used for implementing dividers over GF
(p/sup n/). Generic dividers have been synthesized in the general case of GF (p/sup n/) and …
