Analysis and modeling of power distribution network and decoupling network design strategies for high speed digital and analog VLSI system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)Today’s high speed digital and analog VLSI systems are operating in GHz frequency range. With high switching rate of the devices, power distribution network (PDN) impedance causes ripples in power supply. If PDN is not ... -
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. ... -
Carrier recovery in software defined radio (SDR)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)The work presented here, deals with the carrier synchronization in digital communication system. The transmitter and receiver are two separate circuits located at a distance end and rarely share same carrier frequency ... -
Channel estimation and tracking OFDM and MIMO systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)In this thesis, To estimate and track the slow Time varying channels in OFDM and MIMO systems. In first part: we have used a two-dimensional recursive least square adaptive channel estimation technique is used. In orthogonal ... -
Design of an analog phase shifter at X-band for radar and telecom applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)When examining a monthly bank account statement it is not only the number below the bottom line that matters. Whether that number has a minus or plus in front of it is also crucial. For many technical issues, the sign ... -
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 ... -
Statistical co-analysis, robust optimization and diagnosis of USB 2.0 system for signal and power integrity
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)Signal Integrity (SI) and Power Integrity (PI) are the most critical issues as semiconductor industry is moving towards higher operational speeds. Signal integrity and power integrity are such issues that should be looked ...
