Analysis of a Noncoherent UWB Receiver for Multichannel Signals
The authors present a detailed analysis of a previously introduced Multi-Channel Autocorrelation Receiver (MC-AcR) for multichannel Ultra-WideBand (UWB) signals. Performance measures are introduced and discussed to provide insight in the invertibility problem for this receiver, the capability to separate the multichannel UWB signal. The results can be used for understanding the impact of hardware imperfections and for the optimization of signal parameters. This paper deals with the analysis of a previously introduced MC-AcR for multichannel UWB signals,, where analog hardware is used to estimate samples of the Auto-Correlation Function (ACF) of the received signal, and digital backend processing to separate the channels of the UWB signal.
