Abstract
In this study, we analyze the interference pattern of multi-user direct sequence ultra-wideband (DS-UWB) signals on unified S-band telemetry tracking and control (USB TT and C) systems. Due to the overlay nature of UWB signals, it's inevitable that UWB signals will cause interference to USB TT and C systems. Compared to the bandwidth of DS-UWB signals, USB TT and C can be regarded as a narrowband system and there are two main interference patterns: pulse interference and white noise interference, which is determined by some of the parameters of two systems. Hence, the relationship between these parameters and the interference pattern can be analyzed and use the results to design two systems to cause minimum interference and achieve spectrum coexistence.
