5.1.1. Running the 5G LDPC IP C++ Models

The encoder file is: LdpcEncoder_cTB.c. The decoder file is LdpcDecoder_fxp_cppTB.cpp.
  1. For the decoder, run: 
    prompt> g++ LdpcDecoder_fxp_cppTB.cpp
prompt> ./a.out
snr = 1.60
DecodedIters = 7
BitErrors[7] = 0
et_pass = 1
  2. For the encoder, run: 
    prompt> g++ LdpcEncoder_cTB.c
prompt> ./a.out <testcase>
<testcase> =  0:
  z = 8;
  base_graph = 1; // BG#2
  code_rate = 0; // 1/5
  kb = 6;
  break; 
<testcase> =  1:
  z = 36;
  base_graph = 1; // BG#2
  code_rate = 2; // 2/5
  kb = 8;
  break;
<testcase> =  2:
  z = 104;
  base_graph = 0; // BG#1
  code_rate = 7; // 8/9
  kb = 22;
  break;
<testcase> =  3:
  z = 384;
  base_graph = 0; // BG#1
  code_rate = 1; // 1/3
  kb = 22;
    For example, type ./a.out 0, then you see: 
    prompt> tc=0
 prompt> output file: cw.z=8.bg=1.cr=0.kb=6.txt
  3. To check the result, type: 
    prompt> diff ./cw.z=8.bg=1.cr=0.kb=6.txt ./txt
