Low-power multi-ported register file for digital signal processors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Digital Signal Processors (DSPs) also come under the category of processors in which Multi-ported register files can find their applications widely. Most of the DSP applications do not benefit from further speeding-up after ...
Application of compressive sensing to tow-way relay channel estimation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
An Amplify and Forward Two-Way Relay Network is one where two nodes transmit data to
each other via an intermediate relay. The relay amplifies the superimposed data from both
the nodes before sending it to both the nodes. ...
Design & layout of a low voltage folding & interpolation ADC for high speed applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC) plays a vital role
in mixed analog signalling, communication and digital signal processing world. Now a day,

FPGA implementation of multiband and multimode modem for software defined radio (SDR)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Now a days Software Defined Radio(SDR) is becoming popular for wireless communication
because of it’s flexibility to change as per requirement through software. The work presented
here describes the different methods of ...
FIR filter for high speed 60 GHz wireless communications.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In this thesis report the design and implementation of the FIR filter at 5 GS/s presented. IEEE 802.15.3c standard declared unlicensed band from 57 to 66 GHz. This 60 GHz wireless communication transmitter uses interpolator ...
Phonetic segmentation: unsupervised approach
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Phonetic segmentation can find its potential application for Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) Synthesis systems. In this thesis, we propose use of different spectral features viz., Mel Frequency ...
Vocal tract length normalization for automatic speech recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
Various factors affect the performance of Automatic Speech Recognition (ASR) systems. In this thesis, speaker differences due to variations in vocal tract length (VTL) are taken into account. Vocal Tract Length Normalization ...
Learn Graph Laplacian for Sparse Frequency Domain Representation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2017)
"Learning of graph topology plays an important role in processing structure and unstructured data which can be represented as graph signals. Graph topology for a given graph signal is not always readily available from the ...
Transmultiplexer design using different filters
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Transmultiplexer is one of the applications of Filter banks, which is used to transmit many signals simultaneously through a single channel and so that to separate at receiving end. Design of transmultiplexer using prototype ...
Oblique projection operator
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
This thesis presents the understanding usefulness of Oblique Projector in signal processing like signal recovery, signal representation and reconstruction. This thesis also presents the different recursive oblique projector ...
