抜粋

Layered LDPC decoding algorithm is known to achieve high Bit Error Rate (BER) performance and high throughput for LDPC decoders. However, for ISDB-S2 (Integrated Services Digital Broadcasting via Satellite - Second Generation) LDPC decoder, applying layered algorithm directly will result in data conflict problem. In this paper, a novel selective recalculation method is proposed to solve the data conflict problem. It determines the inaccurately calculated values based on a recalculation decision rule, and correct them accordingly. By applying this selective recalculation method, the layered algorithm can achieve conflict free BER performance. Simulation results demonstrate that the proposed method can achieve 0.1dB gain for the code with most conflicts in ISDB-S2, under the same BER performance compared to the previous strategy to solve data conflict problem.
