An Efficient LDPC Encoder for CMMB Using RU Method
Zhibin Zeng, Yuan Feng, Xiangran Sun · Procedia Engineering · 2012
An efficient LDPC encoder based on classic RU method is presented for CMMB in this paper. The RU method uses an optimized greedy algorithm for approximate triangulation with sparse matrix of LDPC codes. Simulation results show that this improved method can reduce encoding complexity effectively and save hardware resource for implementation.
