Soft-DVB: A Fully-Software GNURadio-based ETSI DVB-T Modulator

چکیده
Typical architectures for digital video broadcastingterrestrial (DVB-T) modulators are based on task-specific hardware to adapt the baseband audio/video signal to the radio frequency terrestrial channel. This paper describes the architecture of a fully-software, real-time modulator for DVB-T signals named Soft-DVB, which makes use of a software section developed from scratch by the authors and integrated into the GNURadio framework. Implementation results are shown and possible application scenarios are outlined. The excellent performance achieved by Soft-DVB proves the feasibility of a fully-software architecture on a standard PC platform as a viable and profitable solution for next-generation DVB-T (DVB-T2) modulators.
