    • Bidding strategies for dynamic spectrum allocation 

      Dhumal, Neha (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      Dynamic Spectrum Allocation is the process of assigning spectrum licenses in terms of the chunks of the spectrum band to the Wireless Service Providers (WSPs). This allocation assignment is being done as per the WSPs' ...

    • Broadband microstrip antennas with switchable polarizations 

      Bombale, Uttam Laxmanrao (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      Microstrip antenna consists of a patch of metallization on grounded substrate. These are low profile, lightweight antennas, most suitable for aerospace and mobile application. They are replacing many conventional antennas ...

    • Design of a novel high linearity down conversion mixer for GSM band applications 

      Srinaga, Nikhil N. (Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
      Double balanced Gilbert cell mixer (GCM) is the mostly used kind of mixer as it provides conversion gain and has port to port isolation. This mixer lacks in linearity and noise figure which are to be taken care in designing ...

    • Design of digital accelerometer based seismic sensor node 

      Sharma, Nisha (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      The aim of Design of Digital Accelerometer based Seismic Sensor Node is to propose a design for wireless sensor network for exploring the sub-surface region of the moon by studying the seismic waves generated over there. ...

    • Investigation on multi-band fractal antennas for satellite applications 

      Shah, Milind (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      Remote sensing is a very important application of satellite communication. In remote sensing applications, multiple frequencies are utilized. Use of different antennas for different frequencies is a complex task and so use ...

    • Radiation analysis of microstrip active (amplifier) and passive (antenna) structures 

      Dhoot, Vivek (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      Analysis of radiation from a microstrip amplifier and a newly proposed microstrip antenna is presented. Microstrip amplifier is analyzed replacing the MMIC structure by an equivalent S2P model and remaining portion being ...
