Executive Summary

UWB is a high data rate, short range technology .It transmits the information over a minimum bandwidth of 500 MHZ. Modern UWB systems use Modulation techniques such as OFDM (Orthogonal Frequency Division Multiplexing). The MB-OFDM proposal is selected for UWB system model. MultiBand OFDM (MB-OFDM) is a short-range wireless technology that permits data transfers at very high rates, between 53.3 and 480 Mbps. For the requirement of Multiband-OFDM system, the processor should work on a few hundred MHz, which makes it difficult to implement. And since the system targets for the wireless portable devices, small area and low power consumption are also imperative. Therefore a 8-way parallel architecture based on bi-orthogonal encoder is proposed in this paper.
