BER performance of transmitted-reference UWB systems with notch filter in the presence of inter-pulse interference and partial-band interference

In this paper, we propose an ultra wideband (UWB) system which, through the use of transmitted reference (TR) and a finite impulse response (FIR) or infinite impulse response (FIR) notch filter, is able to mitigate both narrowband interference (NBI) and inter-pulse interference (IPI). The bit-error rate (BER) performance of the auto-correlation receiver (ACR) is investigated over an IEEE802.15.4a wireless channel. The NBI arising from the existing wireless services is modeled as partialband Gaussian noise. Numerical results show that the proposed TR-UWB receiver has stable BER performance against variations in various system parameters over wireless channels.
