A Frame Self-Synchronization Method for Low-Density Parity Check Code
Sen Li · Electronics Optics & Control · 2009
The decoding convergence's difference of Low-Density Parity Check Code(LDPC) under frame synchronization and desynchronization was investigated.Based on the difference of convergence,we presented a frame self-synchronization method by trial-decoding under position-shift.The principle of shift preselection was discussed in detail for decreasing the complexity of synchronization.Simulation results showed that the self-synchronization method has better reliability and lower cost.
