  1. USE OF MULTITHRESHOLD DECODERS IN EARTH REMOTE SENSING SYSTEMS OvechkinG.V.,OvechkinP.V. The Ryazan state radio engineering university The specialized site of SRI RSA on multithreshold decoders: www.mtdbest.iki.rssi.ru

  2. 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 The specialized site of SRI RSA on multithreshold decoders: www.mtdbest.iki.rssi.ru

  3. The equipment of reception-transmission data in ERS systems • High transferring speed of transfer • Effective error correction algorithms Noise Requirements to the equipment of reception-transmission data in ERS systems: The specialized site of SRI RSA on multithreshold decoders: www.mtdbest.iki.rssi.ru

  4. 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 The basic advantages of multithreshold decoders The specialized site of SRI RSA on multithreshold decoders: www.mtdbest.iki.rssi.ru
