Abstract :
This paper proposes a ranging algorithm for impulse-radio ultra-wideband signals compliant with the IEEE 802.15.4a standard. The algorithm is suited for non-coherent receivers and is implemented in digital form. The achievable ranging accuracy depends on the sampling rate. Ranging errors on the order of 40 cm are obtained with a rate of 1 GHz at SNR=20 dB.
