Abstract :
This paper presents a general method for obtaining the exact power spectra of generic time hopping modulated signals. Based on a point process approach, it provides simpler proofs for existing results and a powerful rigorous and at the same time systematic tool for computing the spectra of more complex time-hopping models. Spectrum formula are easy to understand and the contribution of each component of the model appears explicitly
