The PSD analysis of UWB time hopping impulse radio multi-user aggregate signals

This paper studies the power spectrum density (PSD) of ultra wideband (UWB) time hopping (TH) multi-user aggregate signals with asynchronous transmission and with synchronous transmission. TH codes under consideration are deterministic period code and random integer code. Two UWB modulations, TH pul...

Zusammenfassung:This paper studies the power spectrum density (PSD) of ultra wideband (UWB) time hopping (TH) multi-user aggregate signals with asynchronous transmission and with synchronous transmission. TH codes under consideration are deterministic period code and random integer code. Two UWB modulations, TH pulse position modulation (PPM) and TH pulse amplitude modulation (PAM), are considered in this paper. The distribution of the time delay of UWB asynchronous transmission can dominate the PSD of aggregate signals. The main system parameters, which determine the PSD of UWB aggregate signals, are investigated in detail.
