    • Enhancing data efficiency in OFDM (IEEE 802.11a) using equalization (11A) 

      Reddy, S. Gangadhar (Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
      IEEE 802.11a OFDM signal passed through a dispersive channel introduces ISI & ICI. To avoid ISI & ICI, cyclic prefix (guard interval) is introduced between the OFDM symbols. But the cyclic prefix contributes about 20% ...
    • Frequency offset estimation in OFDM signals using particle filtering along with resampling methods 

      Jayanthi, V. Ravisankar (Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
      Frequency offset is one of the main effects the Bit Error Rate(BER) in orthogonal frequency division multiplexing (OFDM). There are many applications which depend on OFDM. The present method describes the estimation of ...
    • Orthogonal frequency division multiplexing synchronization techniques 

      Ravikanth, Sivangi (Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
      Synchronization plays a major role in the design of a digital communication system. Essentially, this function aims at retrieving some reference parameters from the received signal that are necessary for reliable data ...
    • Pulse shaping for linear time varying channels 

      Doshi, Savankumar (Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
      Pulse shaping is the one of the important an critical area for wireless communication. In this article we show the relation between pulse shaping for wide sense stationary uncorrelated scattering (WSSUS) channels and the ...
    • Study of MPLS traffic engineering with constraint-based routing 

      Modi, Bhavesh (Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
      Multi-protocol Label Switching (MPLS) is fast becoming popular for future communication networks running applications demanding high speed and Quality of Service. In this work, we have studied the evolution of MPLS, various ...
