Clock accuracy analysis for a coherent IR-UWB system
The performance of a duty-cycled coherent impulse radio UWB system is typically dominated by the accuracy of its timing references. In this paper, a timing analysis is presented for an IR-UWB system to specify the accuracy requirements for the internal clocks of the transceiver. A possible clock generation unit is proposed to realize the coherent reception and improve sensitivity and SNR performance. The analysis is performed for an IEEE802.15.4a compliant data packet, however, can be extended to other IR-UWB standards easily.
