The authors study the performance of multi channel transmission over the multi path & multiband-OFDM based ultra-wideband MIMO communication system over multiple-antenna fading channels with linear receivers. They show that, under iterative linear detection and decoding, one can achieve full diversity with a special class of space-time precoders. They then study the outage probability at the output of the linear detector that determines the theoretical performance of coded modulations with such receivers. Finally, symbol and word error rate performances under Monte Carlo simulations are reducing the power consumption and complexity of a Multi Band Orthogonal Frequency-Division Multiplexing (MB-OFDM) Ultra WideBand (UWB) system by applying ideas from pulsed UWB systems.
