Abstract: This thesis presents the design methodology for the analog circuits using the genetic algorithm. Matlab is used as a tool to implement the GA (Genetic Algorithm) to analog circuits design problems as it is considered to be easy and robust with powerful features. Several analog circuits like operational amplifier circuits (inverting and non-inverting amplifiers), active filters and multistage amplifier circuits have been designed using the proposed genetic algorithm.

Abstract: As electrical power industry enters the new century, Computer-based Supervisory Control and Data Acquisition (SCADA) systems have been evolved from standalone, traditional compartmental operations into networked architectures that communicate through computer networks across large distances.

Abstract: A major challenge in broadband MIMO-OFDM system is how to obtain the Channel State Information (CSI) accurately and promptly for coherent detection of information symbols and channel tracking. This thesis formulates the channel estimation problems for MIMO-OFDM systems and proposes a pilot-tone based estimation algorithms. The complex equivalent baseband MIMO-OFDM signal model is derived using matrix representation.
