Abstract
Impulse-Radio Ultra-Wideband (IR-UWB) emerged as a new wireless technology because of its unique characteristics. Such characteristics are the ability to support rich-multimedia applications over short-ranges, the ability to share the available spectrum among multi-users, and the ability to design less complex transceivers for wireless communication systems functioning based on this technology. In this thesis a novel noncoherent IR-UWB receiver designed to support multiple-access is proposed. The transmitter of the proposed system employs the noncoherent bit-level differential phase-shift keying modulation combined with direct-sequence code division multiple-access. The system is investigated under the effect of the additive white Gaussian noise with multiple-access channel. The receiver implements bit-level differential-detection to recover information bits. Closed-form expression for the average probability of error in the proposed receiver while considering the channel effects is analytically derived. This receiver is compared against another existing coherent receiver in terms of bit error rate performance to confirm its practicality. The proposed receiver is characterized by its simple design requirements and its multiple-access efficiency.
