“…Since orthogonal pulses can be transmitted simultaneously without mutual interference, orthogonal pulse set-based IR-UWB systems have the potential to achieve a higher data rate than the conventional IR-UWB systems . Most of the mathematical functions for the design of orthogonal UWB pulses such as the Haar function [55], the modified Hermite polynomial (MHP) function [22][23][24]56], and the prolate spheroidal wave function (PSWF) [57,58], etc. involve complicated math models and power hungry hardware implementation [59].…”

With technological advances in the field of communication, the need for reliable high-speed data transfer is increasing. The deployment of large number of wireless sensors for remote monitoring and control and streaming of high definition video, voice and image data, etc. are imposing a challenge to the existing network bandwidth allocation for reliable communication. Two novel schemes for ultra-wide band (UWB) communication technology have been proposed in this paper with the key objective of intensifying the data rate by taking advantage of the orthogonal properties of the modified Hermite pulse (MHP). In the first scheme, a composite pulse is transmitted and in the second scheme, a sequence of multi-order orthogonal pulses is transmitted in the place of a single UWB pulse. The MHP pulses exhibit a mutually orthogonal property between different ordered pulses and due to this property, simultaneous transmission is achieved without collision in the UWB system, resulting in an increase in transmission capacity or improved bit error rate. The proposed schemes for enhanced data rate will offer high volume data monitoring, assessment, and control of wireless devices without overburdening the network bandwidth and pave the way for new platforms for future high-speed wireless sensor applications.

“…Aside from the original PPM, other modulation techniques have been proposed for UWB including the use of phase, amplitude, On-Off-Keying (OOK), pulse shape, and any combination of them [28,29,30,31]. Equation 2.5 shows a generic form of a transmitted symbol for DS-UWB.…”

“…Equation 2.5 also covers modulation which combine different sources of differentiation. One example is the use of combined pulse shape and position modulation (PPM-PSM) [30]. In this case, the value of both p u,n (t) and d u,n change depending on the transmitted information.…”

First and foremost, I would like to thank my supervisor, Dr Lau Chiew Tong, for his constant support, guidance, and patience, from the first time we worked together for my undergraduate's final year project until today. I would also like to thank Dr Benjamin Premkumar, for all his advises and the many encouragements that I have received throughout all these years. Special thanks to my wife for all the love, support, and understanding. Without these, I would not have the strength to complete this research. I would also like to take this opportunity to thank my parents for their endless encouragements, and my brother for all his help in proofreading all my publications and this thesis. Finally, thanks be to God, for the many gifts and blessings that I have received, and for giving me the strength and energy to work on this research.
