Golay coding link BER simulation¶

As we know the Down link of voyage 1 use the Golay coding when if fly pass by the Jupiter and Saturn.Then we add the Golay encode and decode module to the communication chain, first step we use Golay(23,12,3), the coding rate is 12/23.

Communication chain of BPSK with Golay coding

The simulation program interface using Golay coding is shown below:

The second step we change the coding parameter with Golay(24,12,3), then we simulate again, and we got two groups BER data, which is shown as following:

BER curve with two Golay coding

We can see that the two Golay nearly have the same coding gain at BER = 1exp-5, the coding gain is about 2dB.
