In this paper, the authors analyze the performance of an Ultra-WideBand (UWB) communication system in the presence of pulsed Gaussian jamming. They derive the optimum and suboptimum receivers for such a system and evaluate the system performance. Two low complexity suboptimum receivers are designed using a Gaussian approximation (linear) and the Locally Optimum Bayes Detection (LOBD) algorithm (non-linear). Numerical results show that the nonlinear receiver outperforms the linear receiver when the jamming interference is strong. However, when the background noise is weak (high SNR), due to the Gaussian nature of impulsive interference, the non-linear receiver performance converges to that of the linear receiver.
