Cyclic Spectral Analysis of UWB-IR Signals

Cyclic Spectral Analysis of UWB-IR Signals

A unified, matrix-based, stochastic method for cyclic spectral analysis of ultra-wideband impulse radio signals, based on their Markov chain representation, is proposed. Explicit expressions are obtained for the cyclic spectrum of pulse position modulation and pulse amplitude modulation with time-ho...

Zusammenfassung:A unified, matrix-based, stochastic method for cyclic spectral analysis of ultra-wideband impulse radio signals, based on their Markov chain representation, is proposed. Explicit expressions are obtained for the cyclic spectrum of pulse position modulation and pulse amplitude modulation with time-hopping and direct sequence coding, respectively. Some theoretical and graphed results for the spectral correlation characterization of these signals are presented, as well.
