Abstract
In this contribution we develop a Multiple-Input Multiple-Output (MIMO) Impulse Radio Ultra Wide Band (IR-UWB) transceiver for Orthogonal signalling over (baseband) multipath faded MIMO channels. The proposed Maximum-Likelihood receiver results to be "partially coherent", since it is optimized to work without any information about channel coefficients, and it is based on the knowledge of the arrivals' times of the transmitted signals' replicas. The behavior of the proposed transceiver has been evaluated via three suitable versions of the Union-Chernoff Bound related to several indoor and outdoor propagation scenarios, and these limits are considered to introduce a novel family of unitary orthogonal Space-time Block Codes (e.g., the Space-Time OPPM (STOPPM) codes), that are able to attain maximum diversity and coding gains. © 2007 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
