    • Multirate signal processing in digital communications 

      Arya, Krishna Kumari (Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
      Fundamentals of multirate signal processing and perfect reconstruction filter banks are revisited. An attempt is made to develop a good understanding of concepts by connecting the filter bank design issues to the concepts ...

    • New learning based super resolution using contourlet transform 

      Singh, Vineet P. (Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
      new learning based super-resolution reconstruction using contourlet transforms is proposed. contourlet transform provides high degree of directionality. It captures geometrical smoothness along multiple directions and ...

    • Nonuniform sampling and its reconstruction methodologies 

      Bhawsar, Vishal (Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
      Alias-free DSP (DASP) is a methodology of processing signals digitally inside bandwidth that are wider than the famous nyquist limit of half of the sampling frequency. This topic has benefited from a strong research revival ...

    • On size balanced binary search trees 

      Kumar, Anand (Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
      History independent data structures are useful when security and privacy are of primary concern. Even if an adversary gets copy of the data structure, he cannot obtain any additional information beyond its content. Important ...
