17664, 16512) LDPC code is simulated under AWGN channel.The simulation is led on FPGA platform, with Layered Normalized BP-Based decoding algorithm.The shifting of measurement point is under consideration, where the soft information for decoding is inaccurate.LDPC performance under different situations are compared, and performance decreased rapidly with measurement point shifted.The related research results may provide a key basis for LDPC application in NAND Flash controller.
