Introduction to Communication System CT111

Message Encoder and Decoder

  • We made a Program for message passing through the erasure and symmetric channels. It includes an information encoder at the transmitter side using Tanner Graph model.

  • We then design spot checks according to a channel. For each channel received, binary code will be decoded using hard and soft-decision decoding methods.

Include :

  • Problem Statement
  • Research paper that we used for conceptual understanding
  • Code Files in C++ for
    • Binary Erasure channel
      • Hard decision decoding
      • Soft decision decoding
    • Binary Symmetric channel
      • Hard decision decoding
      • Soft decision decoding
  • Output Graph of error-probabilty Vs decoding rate in Matlab
  • Report File includes concept, code explanation, code snippet and debug environment, camparision betweern output graphs using defferent decoding methods.
