Investigations on Online Boundary Variation Techniques for Nearly Constant Switching Frequency Hysteresis Current PWM Controller for Multi-Level Inverter Fed IM Drives
(2018-02-22)
In DC to AC power conversion, voltage source inverters (VSI) based current controllers are usually preferred for today’s high performance AC drive which requires excellent dynamic and steady state performances at different ...
Spatially Correlated Data Accuracy Estimation Models in Wireless Sensor Networks
(2018-02-10)
One of the major applications of wireless sensor networks is to sense accurate and reliable data from the physical environment with or without a priori knowledge of data statistics. To extract accurate data from the physical ...
Content Distribution in Social Groups
(2018-01-29)
We study Social Groups consisting of self-interested inter-connected nodes looking for common content. We can observe Social Groups in various socio-technological networks, such as Cellular Network assisted Device-to-Device ...
Architecture and Design of Wide Band Spectrum Sensing Receiver for Cognitive Radio Systems
(2018-01-03)
To explore spectral opportunities in wideband regime for cognitive radio we need a wideband spectrum sensing receiver. Current wideband receiver architectures need wideband analog to digital converter (ADC) to sample ...
An Improved Lower Bound for Depth four Arithmetic Circuits
(2018-05-29)
We study the problem of proving lower bounds for depth four arithmetic circuits. Depth four circuits have been receiving much attraction when it comes to recent circuit lower bound results, as a result of the series of ...
Precoding for Interference Management in Wireless and Wireline Networks
(2018-02-27)
Multiple users compete for a common resource like bandwidth to communicate
data in interference networks. Existing approaches in dealing with interference
limit the rate of communication due to paucity of shared resources. ...
Transceiver Design Based on the Minimum-Error-Probability Framework for Wireless Communication Systems
(2018-06-19)
Parameter estimation and signal detection are the two key components of a wireless communication system. They directly impact the bit-error-ratio (BER) performance of the system. Several criteria have been successfully ...
Optical WDM Systems for Multi-point Distribution of Hybrid Signals in Phased Array Radar Applications
(2018-07-16)
Photonics and Optical techniques have advanced recently by a great extend to play an important role in Microwave and Radar applications. Antenna array of modern active phased array radars consist of multiple low power ...
On Design and Analysis of Energy Efficient Wireless Networks with QoS
(2018-06-13)
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 ...
Optimal Mechanisms for Selling Two Heterogeneous Items
(2018-07-04)
We consider the problem of designing revenue-optimal mechanisms for selling two heterogeneous items to a single buyer. Designing a revenue-optimal mechanism for selling a single item is simple: Set a threshold price based ...
