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 ... -
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 ... -
Modular Design Of Microheaters, Signal Conditioning ASIC And ZnO Transducer For Gas Sensor System Platform
(2013-07-16)With the proliferation of industries world-wide, there is a growing need and interest in sensing and monitoring environmental pollutants and monitoring the concentration of chemicals/gases in industrial process control. ... -
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 ... -
Statistical Leakage Analysis Framework Using Artificial Neural Networks Considering Process And Environmental Variations
(2013-07-03)Leakage current and process variations are two primary hurdles in modern VLSI design. It depends exponentially on process and environmental parameters and hence small variations in these result in a large spread in leakage ... -
