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.
