چکیده
This paper investigates the Multi-bandOFDM (MB-OFDM) based Ultra-Wideband for working group on short-range high data-rate Ultra-wide-Band (UWB) communications. An overview of the MB-OFDM PHYlayer 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 (BER) of MB-OFDM over the fading channel. Performance results over realistic UWB channel models are analyzed and compared to a pulsed-OFDM based approach. Although pulsedOFDM was presented in the literature as an enhancement to the MBOFDM approach, simulation results showed that with same redundancy factor, both systems address almost similar BER performance.

On the Perfomance of Multiband OFDM under Log-normal Channel Fading
A modified Saleh-Valenzuela channel model has been adapted for Ultra Wideband (UWB) system. The suggested realistic channel is assessed by its distribution of fading amplitude and time of arrivals. Furthermore, the propagation characteristic has been distinct into four channel models, namely CM 1 to 4. Each are differentiate in terms of cluster arrival rates, rays arrival rate within each clust...

Problem statement: The Multiband Orthogonal Frequency Division Multiplexing (MBOFDM) Based Ultra Wideband system (UWB) is highly susceptible to symbol timing error. Symbol timing estimation in MB-OFDM based UWB is difficult due to the presence of strongest path at delayed instant. Approach: Symbol timing estimation has two steps namely a coarse estimation and a fine estimation. In this study, a...

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...
