Models for UWB pulses and their effects on narrowband direct conversion receivers
A methodology is shown for predicting the effect of pulsed UWB communication waveforms on direct conversion quadrature (I/Q) receivers at baseband by analysis or simulation, making use of mathematical models of UWB pulses, of which several examples are given. The unique characteristics of UWB pulses are used to derive predictions of the UWB interference at baseband using both time- and frequency-domain calculations of the baseband filter's response to the pulses. The final result of this analysis is an estimate of the rise in receiver noise level due to the UWB interference.
