Process variations inducing transistor characteristics mismatch have emerged as major challenge to nano-scale circuit design leading to failure and yield loss of circuits such as sense amplifiers. In this work, these issues ...

OFDM has become a popular technique for transmission of signals over wireless channels. It converts a frequency-selective channel into a parallel collection of frequency flat sub channels, which makes the receiver simpler. ...

Speed and area are two main concerns in the design of modern integrated circuits. With scaling of technology, size of devices reducing and most of the chip area in is covering by interconnects, also, effects of parasitics ...

Coded Cooperation is a burgeoning field of Cooperative Communications. This generates diversity in a new and interesting way. This method integrates cooperation into channel coding. Coded Cooperation allows single antenna ...

Robots are mechanical devices which can be programmed to perform a large variety of tasks. In recent years robots have been applied in fields from painting to complicated surgeries. PUMA 560 is an important class of robotic ...

Synchronization is an essential task for any digital communication system. Without a proper and accurate synchronization method, it is not possible to reliably receive the transmitted data. Synchronization is the first and ...

In this dissertation work, QFT and H-infinity controllers were designed for a vehicle suspension system and their performance is compared and also with a standard PID controller. A suspension system works in uncertainties, ...

Photovoltaics' has gained importance with the failure of conventional energy resources to meet the energy requirements of various sectors. Crystalline silicon dominates the photovoltaic market today primarily due to its ...

Sensitivity and Robustness is the key factor while designing the controller for nonlinear systems. One of the performance objectives for controller design is to keep the error between the controlled output and the set-point ...

Recently, there has been much interest in modulation techniques to achieve transmit diversity motivated by the increased capacity of multiple-input multiple-output (MIMO) channels. To achieve transmit diversity the transmitter ...
