  • Adaptive throughput optimization in downlink wireless ofdm system 
    Youssef Fakhri; Benayad Nsiri; Driss Aboutajdine; Josep Vidal (nternational Journal of Communications, Network and System Sciences, 2008-05-10)
    This paper presents a scheduling scheme for packet transmission in OFDM wireless system with adaptive techniques. The concept of efficient transmission capacity is introduced to make scheduling decisions based on channel ...
  • A new approach for wireless communication systems based on idma technique 
    Awatif Rouijel; Benayad Nsiri; Ahmed Faqihi; Driss Aboutajdine (2010 5th International Symposium On I/V Communications and Mobile Network, 2010-09-30)
    —This paper will propose a novel multiple access technology, called OWDM-IDMA (Orthogonal Wavelength-Division Multiplexing-Interleave Division Multiple Access), which is the combination of OWDM (Orthogonal Wavelength-Division ...
  • Peak to average power ratio analysis for OWDM-IDMA system 
    Awatif Rouijel; Benayad Nsiri; Driss Aboutajdine (2011 International Conference on Multimedia Computing and Systems, 2011-04-07)
    A major drawback of orthogonal frequency division multiplexing interleave division multiple access (OFDM-IDMA) is the high peak to average power ratio (PAPR) of the transmitted signal. In this paper, the basic principle ...
  • Throughput optimization for wireless OFDM system in downlink transmission using adaptive techniques 
    Youssef Fakhri; Benayad Nsiri; Driss Aboutajdine; Josep Vidal (2006 International Conference on Wireless Communications, Networking and Mobile Computing, 2006-09-22)
    In this paper we present a mathematical technique for determining the optimum transmission rate and packet size in wireless system that have multi-carriers for OFDM modulation in downlink transmission. The throughput ...
