Techniques For Low Power Motion Estimation In Video Encoders
(2013-02-12)
This thesis looks at hardware algorithms that help reduce dynamic power dissipation in video encoder applications. Computational complexity of motion estimation and the data traffic between external memory and the video ...
Robust Precoder And Transceiver Optimization In Multiuser Multi-Antenna Systems
(2013-10-04)
The research reported in this thesis is concerned with robust precoder and transceiver optimization in multiuser multi-antenna wireless communication systems in the presence of imperfect channel state information(CSI). ...
Design And Analysis Of Microstrip Ring Antennas For Multi-frequency Operations
(2013-06-18)
In this research we attempted several modifications to microstrip ring/loop antennas to design multi-frequency antennas through systematic approaches. Such multi-frequency antennas can be useful while building compact ...
Low Power Receiver Architecture And Algorithms For Low Data Rate Wireless Personal Area Networks
(2013-09-03)
Sensor nodes in a sensor network is power constrained. Transceiver electronics of a node in sensor network consume a good share of total power consumed in the node. The thesis proposes receiver architecture and algorithms ...
Equalization Algorithms And Performance Analysis In Cyclic-Prefixed Single Carrier And Multicarrier Wireless Systems
(2014-05-21)
The work reported in this thesis is divided in to two parts.
In the first part, we report a closed-form bit error rate (BER) performance analysis of orthogonal frequency division multiple access (OFDMA) on the uplink in ...
Performance Analysis Of Post Detection Integration Techniques In The Presence Of Model Uncertainties
(2013-07-10)
In this thesis, we analyze the performance of the Post Detection Integration (PDI) techniques used for detection of weak DS/CDMA signals in the presence of uncertainty in the frequency, noise variance and data bits. Such ...
Cooperative Communication In Store And Forward Wireless Networks Using Rateless Codes
(2013-08-30)
In this thesis, we consider a cooperative relay-assisted communication system that uses rateless codes. When multiple relays are present, the relay with the highest channel gain to the source is the first to successfully ...
Energy And Channel-Aware Power And Discrete Rate Adaptation And Access In Energy Harvesting Wireless Networks
(2013-01-08)
Energy harvesting (EH) nodes, which harvest energy from the environment in order to communicate over a wireless link, promise perpetual operation of wireless networks. The primary focus of the communication system design ...
