NoC Design & Optimization of Multicore Media Processors
(20180322)Network on Chips[1][2][3][4] are critical elements of modern System on Chip(SoC) as well as Chip Multiprocessor(CMP)designs. Network on Chips (NoCs) help manage high complexity of designing large chips by decoupling ... 
NonInvasive Microwave Hyperthermia
(Indian Institute of Science, 20060118)Presented in this thesis are the following theoretical investigations carried out on the noninvasive microwave hyperthermia of malignant tumours in the human body: Fundamental concepts of electromagnetic wave ... 
Nonlinear Processing Of EEG and HRV Signals For The Study Of Physiological And Pathological States
(20130426)Physiological signals, electroencephalogram (EEG) and heart rate variability (HRV), are generated by complex selfregulating systems. These signals are extremely inhomogeneous and nonstationary, and fluctuate in an irregular ... 
Nonstationary Techniques For Signal Enhancement With Applications To Speech, ECG, And NonuniformlySampled Signals
(20150722)For timevarying signals such as speech and audio, shorttime analysis becomes necessary to compute specific signal attributes and to keep track of their evolution. The standard technique is the shorttime Fourier transform ...

On Design and Analysis of Energy Efficient Wireless Networks with QoS
(20180613)We consider optimal power allocation policies for a single server, multiuser wireless communication system. The transmission channel may experience multipath fading. We obtain very efficient, low computational complexity ... 
On Linear Codes in Projective Spaces
The projective space $\mathbb{P}_q(n)$ of order $n$ over a finite field $\mathbb{F}_q$ is defined as the collection of all subspaces of the ambient space $\mathbb{F}_q^n$. The Grassmannian $\mathcal{G}_q(n, k)$ is the set ... 
On MediaBased Modulation for Wireless Communications
Traditionally, symbols chosen from complex modulation alphabets such as QAM and PSK are used to convey information bits, and complex fades introduced by the channel are viewed as detrimental effects that cause amplitude ... 
On Network Coding and NetworkError Correction
(20180424)The paradigm of network coding was introduced as a means to conserve bandwidth (or equivalently increase throughput) in information ﬂow networks. Network coding makes use of the fact that unlike physical commodities, ... 
On Orthogonal Time Frequency Space Modulation for Wireless Communications
Future wireless communication systems are envisioned to support diverse requirements that include high mobility application scenarios such as highspeed trains, and vehicletovehicle and vehicletoinfrastructure communications. ... 
On Some Questions Involving Prefix Codes
Let A be a finite alphabet and A be the set of all finite sequences of the elements of A. A word is any member of A . A prefix code X is a set of words satisfying the prefix property, i.e., no word in the set is a prefix ...
