In this article, a novel two-way double-relay selection strategy with its bit error rate (BER) performance analysis is proposed. In this novel strategy, as a first step we choose two relays out of a set of relay-nodes in a way to maximize the system performance in terms of BER and complexity. In the second step, the selected relays apply orthogonal space-time coding scheme using the three-phase protocol to establish a two-way communication between the transceivers, which will lead to a significa...

Sleep pattern and posture recognition have become of great interest for a diverse range of clinical applications. Autonomous and constant monitoring of sleep postures provides useful information for reducing the health risk. Prevailing systems are designed based on electrocardiograms, cameras, and pressure sensors, which are not only expensive but also intrusive in nature, and uncomfortable to use. We propose an unobtrusive and affordable smart system based on an electronic mat called Sleep Mat-...

This paper compares the performance of a relay assisted network to the performance given by a classical macrocell network without the presence of relay node schemes. The capacity enhancement provided by a relaying system as a function of the relay antenna height and the propagation environment surrounding the relay nodes is analyzed and discussed in details. The analysis in this work is based on the theoretical Shannon capacity where both measured/experimental path loss and calibrated path loss ...

In this work, we are interested in implementing, developing, and evaluating a time reversal strategy for a multiple-input single-output orthogonal frequency division multiplexing system. This strategy enjoys a good trade-off between the computational complexity and performance in terms of bit error rate where it offers a good coding gain by forming a beam in the direction of the destination at a price of channel state information available at the transmitter. In time reversal technique, a higher...

A novel, programmable, mode-locked fiber laser design is presented and numerically demonstrated. The laser programmability is enabled by an intracavity optical phase-only pulse shaper, which utilizes the same linearly chirped fiber Bragg grating (LC-FBG) from its two opposite ends to perform real-time optical Fourier transformation. A binary bit-pattern generator (BPG) operating at 20-Gb/s and producing a periodic sequence of 32 bits every 1.6 ns, is subsequently used to drive an optical phase m...

Relaying technique is a key technical enhancement in 3GPP LTE-Advanced proposed for the improvement of system performances such as spectral efficiency and throughput. In order to evaluate system performance, propagation path loss models for the links between the Base Station-Relay Station (BS- RS), the Base Station-Mobile Station (BS-MS) and the Relay Station-Mobile Station (RS-MS) must be investigated. This paper compares the Path Loss (PL) models for the RS-MS link to measurement data. The ana...

Relaying technique is a key feature for the 3GPP LTE-Advanced system. In order to evaluate the system performance, path loss models for the links Base Station-Relay Station (BS-RS), Base Station-Mobile Station (BS-MS) and Relay Station-Mobile Station (RS-MS) must be investigated. This paper focuses on the RS-MS link. It studies the impact of the relay position and relay antenna height based on a measurement campaign focusing on Line of Sight (LOS) conditions. Furthermore, it aims to propose a lo...
