Earth remote sensing

Earth remote sensing (ERS) is used for observing the Earth’s surface by the aviation and space systems

ERS data can be used for the decision of tasks in various areas:

  • Cartography
  • City planning
  • Natural resources
  • Agriculture
  • Forestry
  • Ecology
  • Transport
  • Communication

Multithreshold decoders

  • Simplicity of practical realization (Low cost, High reliability, high-speed performance);
  • Effective error correction algorithm;
  • Decoding complexityO(n);
  • Decoding speed up to several Gbit/s
  • Coding gain - 7-8 dB

The multithreshold decoder is the majority decoder
