Abstract
Embodiments of a method and a device are disclosed. In an embodiment, a method for operating an impulse radio ultra-wideband (IR-UWB) device is disclosed. The method involves acquiring a signal, integrating one or more synchronization symbols in a synchronization field of the signal to determine an initial channel impulse response (CIR) measurement, and detecting whether a start-of-frame delimiter (SFD) field of the signal is identified during integration. When the SFD field of the signal is identified, the method further involves ceasing integration of the one or more synchronization symbols, scaling the initial CIR measurement, and determining a final CIR measurement based on the scaled CIR measurement. When the SFD field is not identified, the method further involves incrementing a counter configured to count the number of the one or more synchronization symbols integrated, and continuing integration of the one or more synchronization symbols until the SFD field is identified.
