Performance Analysis of Multiband OFDM UWB Systems With Imperfect Synchronization and Intersymbol Interference

Rake Reception for Uwb Communication Systems with Intersymbol Interference

Recently, ultra wideband (UWB) technology has been proposed for use in wireless personal area networks (WPANs). Under the conditions where such transceivers are expected to operate, intersymbol interference (ISI) will become a significant performance limitation, and improvements to conventional RAKE reception will be necessary. We propose a modified RAKE receiver that finds an optimal balance b...

Coded Multiband OFDM with Tone Interference

We consider the convolutionally-coded Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) system for Ultra Wideband (UWB) communications [1], which operates over quasi-static, frequency-selective wireless channels [2]. Classical bit error rate (BER) analysis techniques for coded systems [3] are not applicable in this setting because the channel is (a) non-ideally interleaved (resulti...

Baseband Implementation and Performance Analysis of the Multiband Ofdm Uwb System

Title of Thesis: BASEBAND IMPLEMENTATION AND PERFORMANCE ANALYSIS OF THE MULTIBAND OFDM UWB SYSTEM Hung-Quoc Duc Lai, Master of Science, 2006 Thesis directed by: Professor K. J. Ray Liu Department of Electrical and Computer Engineering In this thesis, we follow the standard proposal IEEE 802.12.3a to implement the MB-OFDM UWB system in C programming language. We also analyze the system performa...

Performance Evaluation of MB-OFDM based UWB System

This paper investigates the Multi-band OFDM (MB-OFDM) based physical (PHY) layer proposal for IEEE 802.15.3a working group on short-range high data-rate Ultra-wide-Band (UWB) communications. An overview of the MB-OFDM PHY layer architecture with its various parameters is presented and the optimal choice of critical parameters is discussed. Next, we derive the theoretical un-coded Bit Error Rate...
