Wireless communication had a significant evolution over the last few years especially with the progress of 5G networks. In our paper, we investigate the impact of the asynchronism on the performance of a Cognitive Radio (CR) network, using the underlay paradigm. We provide a new theoretical aspect of interference analysis in the context of Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM)...
In this paper, we introduce the impact of non-linear high-power amplifier (NL HPA) on the bit error rate (BER) and on the spectrum efficiency of multicarrier techniques. A comparison between two multicarrier transmission techniques based on cognitive radio (CR) is presented: the classical orthogonal frequency division multiplexing (OFDM), based on cyclic prefix (CP), and the filter bank-based multicarrier...
The Wireless Sensor Networks (WSN) have distributed and embedded nature and they are characterized by strong interactions between their hardware and software parts, therefore, their specification is a complex task. Formal methods need strong skills in mathematics in order to model and analyze WSN applications. However, semi-formal methods are simple and easy to understand. Hence, most of approaches...
Wireless communications are currently undergoing very rapid development, and as a result, the demand for wireless spectrum has been growing dramatically. In this regard, future wireless solutions have to meet multiple needs in terms of spectrum efficiency (SE). Both 5G, the next generation of mobile networks, and Cognitive Radio (CR) came as promising new technologies dealing with those requirements...
In this paper, we investigate the impact of the asynchronismon the performance of a Cognitive Radio (CR) network, using the underlay paradigm. We are also comparing this effectdepending on which modulation technique we are using. Weprovide a new the theoretical aspect of interference analysis in thecontext of orthogonal frequency division multiplexing (OFDM) and the Filter Bank Multicarrier (FBMC)...
Future wireless networks are witnessing a major demand for mobile data, which necessitates reconsidering the design and deployment of their infrastructures. To fill this gap, the next-generation mobile 5G is defined as one of the promising solutions. Although the heterogeneous network, the small cell concept and the Cognitive Radio (CR) are considered as key drive technologies for 5G, the major challenge...
Given the rapid progress in wireless devices and the serious demands of higher communication rate, future solutions for wireless networks have to deal with these needs. Proposed solutions must take into account the limited spectrum resource while keeping the energy efficiency. So, a typical processing will realize a balanced trade off: max-throughput/minenergy consumption. In this paper, our contribution...
