Peak to average power ratio reduction in OFDM systems using selected mapping and statistical redistribution

  Orthogonal frequency-division multiplexing (OFDM) is an attractive transmission technique for high-bit-rate communication systems. One major drawback of OFDM is the high peak-to-average power ratio (PAPR) of the transmitter’s output signal. The selected mapping (SLM) approach provides good performance for PAPR reduction, but it requires a bank of inverse fast Fourier transforms (IFFTs) to generate a set...

Information analysis and geographic information system (GIS) exploitation in a grain silo

  This paper presents on the one hand, the cereal activities in Tunisia and on the other hand, a systemic approach of analysis based on the objective oriented project planning (OOPP) method. The exploitation of the systemic approach enables us not only to analyze and to identify the information of the stock management in a grain silo but also to lead an efficient management of cereal transaction. In...

New distributed platform for intrusion detection based on multi-agents system

  The development and evolution of computer networks, in terms of number of users and services, are making them ever more complex and therefore vulnerable to new types of attacks. Given this complexity of attacks, intrusion detection systems, to monitor the activities of a network or a sensitive computer and to detect abnormal usage of computer resources, are expected to evolve and adapt to changes in user...
