The Design of the Baseband Processor of a Non-coherent UWB Receiver

The design of the baseband processor for a noncoherent ultra-wideband receiver is presented. The design integrates all functions necessary for a stand-alone UWB receiver including packet detection and symbol synchronization. The design does not require any high-speed ADCs, but instead relies on simple circuits in the analog domain to acquire the packet and track the incoming data stream. The design provides extensive feedback to the host system about channel conditions and signal strength. The design has been implemented in a 0.18 mu m process with a baseband power consumption of 3.5 mW.
