|Abstract:||Pseudolites are a technology with the potential of bridging the gap between outdoor and indoor navigation. Despite their potential, pseudolites can cause severe interference problems with non-participating receivers, i.e., devices not designed to exploit this technology. In this paper, the loss caused by pulsed pseudolite signals is determined as a function of the pulse duty cycle and the number of bits employed for signal quantization. Quantization, blanking and noise increase are identified as the main sources of signal degradation. Theoretical results are validated by simulations and experiments performed using commercial GPS receivers. The good agreement between theoretical and experimental results supports the validity of the proposed approach.|
