The paper describes information theoretic capacity of orthogonal pulse based modulation schemes for time hopping ultra wideband (TH-UWB) systems over a multiple access and multipath fading channel. Orthogonal pulse based modulation schemes such as pulse shape modulation (PSM), biorthogonal PSM (BPSM) and a combination of orthogonal pulse position modulation (OPPM) and BPSM have been proposed for reducing inter symbol interference (ISI) and multiple access interference (MAI) as well as for improving system performance. System capacity of TH-UWB systems can be increased by employing these modulations for higher level modulation schemes. The capacity of OPPM-BPSM outperforms PSM and BPSM schemes over a multipath fading channel. The complete mathematical analysis and theoretical simulation results are provided in detail.

“…Wireless communication systems typically operate in multipath fading channels. Without loss of generality, a multipath block fading channel is assumed for TH-UWB signal transmission [108,109]. Specifically, fading is assumed to be constant during channel coherence time and becomes independent after coherence time.…”

Firstly, I would like to express my utmost thanks and gratitude to my supervisor and career role model, Assoc Prof. A. S. Madhukumar, for his invaluable guidance and constant encouragement during my PhD study in NTU. Without his help and patience, this dissertation could not have reached the current stage. It has been a genuine privilege to have the opportunity to do research as a member of his research group. I am grateful to him because he has taught me not only numerous topics in wireless communication but also many different aspects of real life. I have learned a lot from him and I believe he has prepared me well for the future. I also thank Dr. A. B. Premkumar for serving on my committee, offering valuable suggestions and reviewing my works. I hope to be able to benefit from his profound knowledge and experience in the coming years, too. I would like to thank all the faculty members and technicians in Center for Multimedia and Network Technology (CeMNet) for their kind help and generous encouragement. I would also like to thank the School of Computer Engineering for the financial support provided during my research.
