Abstract :
A new LDPC encoder is presented for CMMB in this paper. The encoder uses based on RU method embodies high-efficiency by using the optimized backtracking algorithm. Simulation shows that this method decreases the complexity of encoding and calculation significantly. Implementation of the LDPC encoder for CMMB achieves more efficient encoding rate.
