Oversampled channelized receiver for transmitted reference UWB system in the presence of narrowband interference

An oversampled frequency channelized receiver for UWB radio in a transmitted reference (TR) system is presented. Unlike previous work that assumes a white input noise, this paper includes the effects of the automatic gain controller (AGC) and the analog-to-digital converter (ADC) when large narrowband interference (NBI) is present. A detection method for the frequency channelized receiver when input noise is colored in the TR UWB system is proposed. The proposed receiver significantly outperforms the full band receiver.
