This book is intended to illustrate an art of antenna design technique for wireless communication system, and its development and implementation on field of antenna technology. The endeavor is to impart a working knowledge of the subject not just for students and researchers but for the entire wireless community. This book focuses on designing three types of new broadband antennas. Design analysis has been carried out covering the frequency of IMT-2000 and ultrawideband (UWB). The first two types of the antenna designs adopt contemporary techniques; L-probe feeding, inverted patch...

The context for this book is to present a proficient channel estimation technique for performance improvement and complexity reduction of multiple antenna system. Matrix factorization is applied on LS estimation to reduce a full rank matrix into a simpler form in order to eliminate matrix inversion. Results indicate a significant improvement in SNR compared with LS estimation. The complexity comparison is performed in terms of mathematical operations, which shows that the approach outperforms LS estimation at a lower complexity and represents a good solution for channel estimation ...
