On the Achievable Rates of Ultra-Wideband Systems in Multipath Fading Environments

摘要

In this work, we consider achievable rates for transmission strategies suited to Ultra-wideband (UWB) systems and focus non-coherent receivers (i.e. those which do not perform channel estimation, but may have prior knowledge of the second-order channel statistics). Here we take a UWB system to be loosely defined as any wireless transmission scheme that occupies a bandwidth between 1 and 10 GHz and more than 25% of it's carrier frequency in the case of a passband system.
