Abstract :
Multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) techniques are applied to multiband ultrawideband (UWB) systems to obtain high rate communications over indoor wireless channels. In this paper, we setup a general scenario to investigate the performance of MIMO-OFDM multiband UWB systems without specific coding schemes. We also derive a lower bound of pairwise-error probability (PEP) of an (KNtNrL) system (K bandhopping, Nt transmit antennas, Nr receive antennas and L paths combined) in case of lognormal fading channel.
