    • Channel estimation in OFDM systems 

      Rathore, Hitesh (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      Orthogonal frequency division multiplexing (OFDM) is not a new concept, but its receiver design has constant improvement. OFDM uses available spectrum efficiently and the system provides high data rates. Many standards ...
    • Design and implementation of 128-point fixed point streaming FFT processor for OFDM based communication system 

      Verma, Sunil Kumar (Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
      Fast Fourier Transform (FFT) processors are today one of the most important blocks in communication systems. They are used in every communication system from broadband to 3G and digital TV to Radio LANs. This master’s ...
    • 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% ...
    • Executable specification design and simulation of OFDM based communication system 

      Sa, Sudhir Kumar (Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
      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 ...
    • 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 ...
