Single Frequency Networks (SFN) in Digital Terrestrial Broadcasting

Autor: V. Ricny

Publikováno v: Radioengineering, Vol 16, Iss 4, Pp 2-6 (2007)

The paper deals with principles and properties of single frequency networks of digital television and radio transmitters. Basic definitions and contextual relationships (guard interval, area of SFN, influence of used modulation parameters etc.) are e

Robust detection of audio watermarks after acoustic path transmission

Autor: Xiao-ming Chen, Michael Arnold, Peter Georg Baum

Publikováno v: MM&Sec

This paper presents an algorithm to improve the robustness of audio watermarks after acoustic path transmission. This includes a brief presentation of the variety of signal alterations a watermarked audio track undergo in such a scenario. After prese

Autor: Jochen Hopf, H. Lindenmeier, Leopold Reiter

Publikováno v: IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313).

The new satellite digital audio radio service (SDARS) has already started in USA. The circularly polarized satellite signals are supported by terrestrial transmitters in built-up areas using vertical polarization (see Patsiokas et al., SAE 2001-01-13
