Summary:
In this work, the performance of product LDPC codes with page-based weighted bit-flipping (P-WBF) decoding is evaluated on the two-dimensional magnetic recording (TDMR) channel of which areal density approaching 5.62 Tb/in2. Furthermore, we propose to use multiple bits flipping to improve the decoding speed of P-WBF algorithm. The number of bits flipped can be a constant or inconstant at each iteration decoding. The simulation results show that the performance of P-WBF with multiple bits flipping is better than those of the P-WBF algorithm at small iteration number. However, its performance will suffer at high iteration.
