Description

In our following paper, we find that the shortten codes of DVB-S2 have some problems,this program can provide a good DVB-S2 LDPC code without cascaded BCH codes.

For Chinese learners of LDPC, my recent book "MIMO Multi-Antenna Wireless Communication Systems" has provided detailed design examples for good QC LDPC codes.

Some of designs of our good LDPC codes have applied patents, they can be found in our disclosed patents.

In our recent research for LDPC code design, we found that the bidiagnal matrix in parity check matrix will degrade the BER of the desired codes, including shortten DVB-S2 codes. The main reason is the bidiagnal matrix leads lower weight codes in code set. Our this disclosed program provides a spetial case that can avoid the problem. However, we revised the original code design of DVB-S2. From the BER of our codes, we can see that it is unnecessary for casecaded BCH codes for DVB-S2 channel coding, which makes the implementation of DVB-S2 channel coding to be complex and high cost.
