In the future fifth generation networked society, devices will suffer from the asynchronous multi-carrier effect which impacts the user’s quality of experience. This paper investigates the timing misalignment effect on interference level in the context of a cognitive radio (CR) network. Our study considers both multicarrier techniques orthogonal frequency division multiplexing (OFDM) and filter bank...
Cognitive Radio (CR) Technology has emerged for the future of wireless communications, its key parameters of interest are frequency, power and modulation techniques. The Spectrum Sensing is an important task to determine the availability of the vacant channels. In Multicarrier Communication using Digital Signal Processing Techniques, Filter Bank Multi Carrier (FBMC) has an edge over other technologies...
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...
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)...
In this paper, we present a theoretical analysis of the impact of High Power Amplifier (HPA) Non-Linear Distortion (NLD) on the Bit Error Rate (BER) of multicarrier techniques. For the aim of this study, the Saleh's model was chosen for NL HPA. Two multicarrier schemes are considered: the classical Orthogonal Frequency Division Multiplexing (OFDM) and the Filter Bank based Multi-Carrier (FBMC). According...
