摘要：In this paper, we present a multiband ultra wideband (UWB) system design to realize the interference suppression and improve the bit transmission rate. With reasonable division of the UWB bandwidth, the multiband UWB scheme can improve the spectrum utilization and also the bit transmission rate through the utilization of the multiple frequency bands to transmit the information bit simultaneously. Meanwhile, we employ the offset-stacking (OS) spreading modulation based orthogonal complementary code (OCC) UWB system with SQRT chirp waveform (CW) to resist the multiple narrowband interferences (NBIs), multiple access interference (MAI), and multipath interference (MI) together. Simulation results and analysis validate the efficiency of the proposed multiband UWB scheme in the improvement of the system performance and transmission rate.
