      The communication system using the OFDM principle is today one of the most important application in communication field. This system has various applications from broadband to 3G and digital TV to Radio LANs. This master’s ...

    • 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 design for PAPR reduction in OFDM 

      Jain, Akansha (Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
      Future mobile communications systems reaching for ever increasing data rates require higher bandwidths than those typical used in todays cellular systems. By going to higher bandwidth the (for low bandwidth) at fading ...
