Spectral Analysis of UWB Signal Based on Combined Modulation Scheme with Time-Hopping Code
This paper present a uniform signal model of two combined modulation schemes in ultra-wideband (UWB) system, which are combined bi-phase shift keying and pulse shape modulation (BPSK-PSM) and combined on-off keying and pulse shape modulation (OOK-PSM). Both analytical expressions and simulation results for the power spectral density (PSD) of the proposed schemes with time hopping code are provided. The contrast analysis between two schemes and the impact of different time hopping code on the PSD are also discussed. Theoretical analyses and simulation results show that designing a set of proper orthogonal pulses is very important in UWB system based on pulse shape modulation (PSM) scheme.
