For Wireless Personal Area Network (WPAN) systems, resource allocation between several users within a piconet and the coexistence of several piconets are very important points to take into consideration for the optimization of high data rate Ultra Wide Band (UWB) systems. To improve the performance of the Multi Band OFDM (Orthogonal Frequency Division Multiplex) solution proposed by the Multi B...

In logistics management, selecting the carriers to deliver freight is a critical process for global enterprises. This paper determines the optimal carrier selection based on a multi-commodity reliability criterion for a logistics network subject to budget. Traditionally, a logistics network includes nodes and routes connecting the supplier and customer. Along each route, several carriers are av...

This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...

This paper reports on a new class of equalisation/detection for Wideband Multiple Input Multiple Output Communications Systems (MIMO). The proposed scheme is somewhat akin to a multi-carrier MIMO system, and more precisely, builds upon a Single Carrier Frequency Domain Equalised (SCFDE) MIMO System. At the core of our system lies a novel concept of iterative self-reused equalisation/detection (...

Multi-carrier systems based on both discrete multi-tone and filtered multi-tone architectures are investigated for application to asynchronous multi-user communications. Multiplexing of users is implemented by assigning a sub-set of the available carriers to each user. Communications are asynchronous, meaning that the signals belonging to distinct users propagate through independent frequency s...

An efficient ARQ scheme based on the packet combining technique is investigated for multi-carrier modulation systems. In multi-carrier modulation systems, several subcarriers are used for high data rate transmission and their individual received signal quality becomes different from one subcarrier to others in a frequency selective fading channel. Therefore by changing the assignment of data to...

Timing and carrier synchronization is a fundamental requirement for any wireless communication system to work properly. Timing synchronization is the process by which a receiver node determines the correct instants of time at which to sample the incoming signal. Carrier synchronization is the process by which a receiver adapts the frequency and phase of its local carrier oscillator with those o...

this paper introduces an indirect adaptive fuzzy sliding mode controller as a power system stabilizer for damping local and inter-area modes of oscillations of multi-machine power systems. this controller is designed based on the combination of sliding mode controller and the fuzzy logic systems. the fuzzy systems are used to approximate the unknown functions of power system model. generator sp...
