Abstract

The power spectral densities of UWB impulse radio systems with pulse position modulation (PPM) consist of both continuous spectra and discrete frequency spikes. These discrete spikes cause interferences to narrowband systems and deny the harmless coexistence of PPM UWB systems and narrowband systems. To suppress these discrete spikes, in this paper, a random pulse carrier phase jitter (PCPJ) technique is presented and applied to PPM UWB signals. Both theoretical analyses and simulations are carried out and the obtained results show that the proposed technique can effectively suppress the frequency spikes, increase the transmitted power, and thus improve the performance of PPM UWB systems. © 2010 IEEE.
