Abstract:

This paper analyzes comparison between the Multi-band-OFDM (MB-OFDM) based Ultra-Wideband communication and Multi-band pulse OFDM UWB communication. An overview of the MB-OFDM PHY layer architecture with its various parameters is presented and the optimal choice of critical parameters is discussed. It is shown that, while pulsed OFDM has superior or comparable performance to MB-OFDM in multipath fading channels, it also has intrinsic low-complexity and power consumption advantages compared with MB-OFDM. To establish this fact, we describe an example design for the IEEE 802.15.3a Standard and present full simulation results for the UWB indoor propagation channels provided by the IEEE 802.15.3a Standard activity committee. 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 pulsed- OFDM was presented in the literature as an enhancement to the MB-OFDM approach; simulation results showed that with same redundancy factor, both systems address almost similar BER performance.
