Abstract In this paper, two typical high throughput decoding algorithms for QC-LDPC codes are presented: turbo-min-sum-product algorithm and parallel-weighted-bit-flipping algorithm. Their performance are compared in three aspects: decoding speed, hardware complexity, and error rate. In order to achieve high-throughput, a novel time scheduling for parallel-weighted-bit-flipping algorithm is proposed. Computer simulation confirms the effectiveness of two algorithms.
