In this contribution we develop a single Multiple-Input Multiple-Output Impulse Radio UWB (IR-UWB) transceiver for Orthogonal (OPPM) data transmitted over (baseband) multipath faded MIMO channels. The proposed Maximum-Likelihood receiver results to be "partially coherent", because it is optimized to work without any information on the path gains, but only on the knowledge of the arrivals' times of the transmitted signals' replicas. The performance of the proposed transceiver are evaluated via
