      Hello sir,
      This is Peerla Naveen currently pursuing a BTECH degree from VIT University, Chennai. From the examples, I designed the LDPC-Qam-Ofdm FSO link. When I Simulate it I can get the proper constellation diagram but I can’t find the changes in BER values it remains constant for Whatever conditions are given.
      I am attaching the zip file below pls look into it and try to help me in solving it.

      Dear Peerla,
      You need to reduce the FSO range to about 200m also you need to set properly the BERT bit rate and the n/k parameter in the LDPC to allow correct bit rate for the QAM Sequence Generator.
