This paper shows the range improvement achieved using Multiple-Input Multiple-Output (MIMO) in line with jointly encoding the data over subcarriers or across OFDM symbols for Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) ultra wideband (UWB) System. The framework adopted can be for any coding scheme such as Space-Time-Frequency Codes (STFC), Space Time or Space Frequency code. Theoretical derivations are provided based on Saleh-Valenzuela fading model which characterize the random clustering property of UWB channels. The range and pairwise error probability(PEP) improvement obtained from the diversity gain regardless of any type of coding scheme using MIMO-OFDM system through increasing the number of jointly encoded subcarriers, jointly encoded OFDM symbols, or the number of Antennas is investigated and compared with that of conventional Multiband OFDM UWB system. The relation between coding gain and channel model parameters of UWB channels is also discussed.
