LANDEROS-AYALA, Salvador; CHAVEZ-CARDENAS, Sergio A.  and  GONZALEZ-SANCHEZ, Juan C.. Analysis of Standards Efficiency in Digital Television Via Satellite at Ku and Ka Bands. Ing. invest. y tecnol. [online]. 2013, vol.14, n.3, pp.335-353. ISSN 2594-0732.

In this paper, an analysis on the main technical features of digital television standards for satellite transmission is carried out. Based on simulations and link budgets, the standard with the best operational performance is defined, based on simulations and link budget analysis, as well as a comparative efficiency analysis is conducted for the Ku and Ka bands for both transparent and regenerative transponders in terms of power, bandwidth, information rate and link margin, including clear sky, uplink rain, downlink rain and rain in both.

Keywords : digital television; satellite; standards; transponder.
