    • Applications of deep-learning at digital communication receiver 

      Nanavati, Tilak Digantkumar (Dhirubhai Ambani Institute of Information and Communication Technology, 2020)
      Modulation and demodulation are fundamental modules for communication systems. The modulation techniques — Offset QPSK (OQPSK), p/2 BPSK, p/4 QPSK and GMSK — are frequently applied in the power-constrained wireless ...

    • Beamforming using learning based algorithms 

      Parekh, Naitik (2020)
      With an increasing number of subscribers to the terrestrial cellular satellite-based services, there is a resultant rise in the demand for the data rate, and there is a growing need for advanced antenna and signal processing ...

    • Comparison and analysis of channel coding schemes for 5G mobile communication 

      Gupta, Naimishi (Dhirubhai Ambani Institute of Information and Communication Technology, 2020)
      This thesis aims to do a Detailed investigation of the performance of Convolutional, Turbo, Low-Density Parity-Check (LDPC), and Polar codes which are the high-performance channel coding schemes for 5G mobile communication. ...

    • Defending machine learning models against adversarial attacks using GANs 

      Malaviya, Shubham M. (Dhirubhai Ambani Institute of Information and Communication Technology, 2019)
      We have used Generative Adversarial Network (GAN) to defend against adversarial attacks. Pixel-wise and perceptual distance measures for images are used in the GAN training. We have used five different distance measures, ...

    • Framework for adaptive video streamingIn satellite networks 

      N, Sushantini (Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
      Video streaming over satellite networks has to be tactfully handled because of it's inherent characteristic of high latency that leads to inefficiency if feedback mechanismlike TCP is used. Further if the satellite ...

    • Improving the spectral efficiency of Precoded-MIMO Systems 

      Fernandez, Joel (2021)
      Transmit Precoding is used in MIMO systems as it reduces the complexity of the MIMO receiver and simplifies the decoding procedure. A multiple-input multiple-output (MIMO) system with Precoding typically suffers from a ...

    • MIMO reception in Rayleigh and Rician fading with imperfect channel estimation 

      Baranwal, Sweety (Dhirubhai Ambani Institute of Information and Communication Technology, 2019)
      Wireless communication technology has undergone significant improvement over the past decades which has lead to the higher data rates and better bit error rate (BER) performance. There has been increase in the demand for ...

    • Non-Orthogonal Multiple Access 

      K. Sesha, Sai Anudeep (2021)
      At present, the spectrum available in wireless communication systems is limited. To meet the high demands in fifth-generation (5G) wireless communication systems, Non-orthogonal multiple access (NOMA) has been introduced. ...
