Capacity Versus Bit Error Rate Trade-Off in the DVB-S2 Forward Link

Autor: Matteo Berioli, Christian Kissling, Rémi Lapeyre

Publikováno v: EURASIP Journal on Wireless Communications and Networking, Vol 2007 (2007)

The paper presents an approach to optimize the use of satellite capacity in DVB-S2 forward links. By reducing the so-called safety margins, in the adaptive coding and modulation technique, it is possible to increase the spectral efficiency at expense

International audience; Meteoroid impacts shape planetary surfaces by forming new craters and alter atmospheric composition. During atmospheric entry and impact on the ground, meteoroids excite transient acoustic and seismic waves. However, new crate
