Production test method for evaluating the effect of narrow-band interference on data errors in ultra-wide band (UWB) receivers

The recent demand in wireless standards capable of providing short-range, high-speed data transfer has accelerated the growth of the ultra-wide band (UWB). In this paper, we develop a low cost production test methodology that quantifies the effects of "in-band" interference from WLAN (802.11a) on the ability of UWB receivers to correctly decode received UWB signals. The analysis presented shows the effect of "in-band" interference on the probability of error for a received '0' bit and a received '1' bit. Using a RF signal generator in pulsed mode as the transmitter, we show that very low values of probability of error (at low interference levels) can be estimated with fewer number of bits transmitted compared to standard production test methods.
