A Novel Zonal UWB Receiver Structure with Improved Performance in Multiple Access Interference

A novel ultra-wide bandwidth receiver structure is proposed for time-hopping ultra-wide bandwidth wireless signal detection in multiple access interference channels. In ideal free-propagation channels, the zonal receiver always meets or outperforms the conventional matched filter UWB receiver, the recently proposed soft-limiting UWB receiver and its enhanced version, the adaptive threshold soft-limiting ultra-wide bandwidth receiver. A new Rake receiver design based on the zonal receiver is proposed for signal detection in multipath channels. Simulation results and analysis show that this new Rake receiver can achieve larger signal-to-interference-plus-noise ratio than the standard matched filter Rake receiver when multipath components are resolvable in UWB channels.
