An Efficient Decoding Algorithm for ISDB-S2

摘要

In this paper, we propose an efficient decoding algorithm for the LDPC codes used in ISDB-S2 (Integrated Services Digital Broadcasting via Satellite - Second Generation).The proposed decoding scheme is hardware-friendly and achieves great improvement on Bit Error Rate (BER) performance.Mathematical induction is used to theoretically verify the correctness of the algorithm.Simulation results for 11 code rates of ISDB-S2 demonstrate that the proposed method can attain a 0.2dB gain under the same BER performance, compared to the existing decoding algorithm.
