Design of Quasi-regular LDPC Codes Encoder Base on Q-matrix
YI Ke-chu · Video Engineering · 2007
A quasi-regular LDPC codes encoder based on Q-matrix is designed and implemented. The encoder is devised on the parity-check matrix of the codes directly,and its complexity is proportional to the length of information bits,which brings the advantage of low difficulty and complexity in hardware implementation. The encoder is realized with FPGA on Quartus II,and its compilation report shows that it employs little logic resource.
