Earth remote sensing SYSTEMS

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

The equipment of reception-transmission data in ERS systems SYSTEMS

  • High transferring speed of transfer

  • Effective error correction algorithms

Noise

Requirements to the equipment of reception-transmission data in ERS systems:

Multithreshold decoders SYSTEMS

  • 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
