The model will contain 3 components:

1. The transmitter
2. The communication line
3. The receiver

The transmitter consists of:

• a LFSR (linear feedback shift register) that implements a primitive polynomial g(x) (e.g. g(x) = x^4 +x+1)
• a register that stores the user data that will be encoded
• some additional logic (gates, flip-flops, etc)

The receiver contains of:

• a LFSR that implements the same polynomial as the transmitter
• an error decoder, that will correct the error, either serially or in parallel
• a register that store that data received from the line
• additional logic

The line will have the possibility to inject error(s) in the stream of bits that go from transmitter to receiver.
