Bit error rates of IR-UWB transceiver types at sub-nyquist sampling rates

Impulse-radio (IR) ultra-wideband (UWB) communications can be achieved with various transceiver architectures. Even though matched filtering is the optimal signal detection technique with Nyquist rate sampling, differentially coherent and non-coherent transceiver architectures may be favorable at lower rate samples. In this paper, we present a unified performance analysis approach for different IR-UWB transceiver types employing various modulation options and using the captured energy statistics at sub-Nyquist sampling rates. Energy capture versus robustness against noise is demonstrated as a trade-off for stored-reference transceivers. Theoretical results are verified via simulations
