Spectral characteristics of DDPM streams and their application to all‐digital amplitude modulation
A new closed-form expression of the spectral coefficients of the digital streams obtained by dyadic digital pulse modulation is presented and validated in this letter. The new expression provides in-depth insight into the spectral properties of dyadic digital pulse modulation, revealing its applicability as an all-digital bandpass amplitude modulation technique. Simulations and measurements on a proof-of-concept dyadic digital pulse modulation amplitude modulator prototype demonstrate the effectiveness of the approach.doi:10.1049/ell2.12050 fatcat:dyoe4muzfzblrd3d63zrpyudgu
