Analyzing the Interference Power of Narrowband Jamming Signal on UWB System

摘要

This paper derives the closed form expression for the interference power of narrowband jamming signal on time -hopping ultra-wide bandwidth system with binary pulse position modulation, assuming the jamming signal as a continuous wide sense stationary zero mean random process and the time hopping codes as a pseudorandom sequence. When the bandwidth of the jamming signal is much smaller than the data rate of UWB system, the approximate expression is presented, based on which some design guides for UWB signal parameters selection are given to reduce the interference power when the jamming signal power and the UWB pulse are fixed. Simulations demonstrate all of the analysis.
