Both Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) Ultra Wideband (UWB) technology and Multiple-Input Multiple Output (MIMO)-OFDM technology have been proposed for future wireless communications systems, supporting data-rates in excess of 100Mbps. These two technologies use two different mechanisms to boost the data-rate. In this paper we analyse the relative advantage, performances and implementation issues of MIMO-OFDM based next generation wireless LAN systems (IEEE 802.11n) and MB-OFDM UWB based next generation wireless PAN systems (OFDM-UWB). In this comparison, we will see that the distinctive differences between OFDM-UWB and IEEE 802.11n technologies lead to significant variations in the performances and different hardware requirements.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
