With the development of LDPC algorithm which has a hardware-friendly trend, the VLSI realization of LDPC decoder is becoming ever the focus of researchers.

Research of Adaptive Resource Allocation Algorithms and LDPC Coding in Multicarrier Systems;

Based on transmitting power and transmitting bits and BER being limited, an adaptive modulation algorithm of irregular and regular LDPC coding in frequency domain MIMO-OFDM system was proposed.

Design of LDPC Encoder in DVB-S2 Based on FPGA;

This paper,based on the introduction of several LDPC codes,analyzes the advantage of multide binary codes,and then describes Tanner graphs and factor graphs for interpretation of sum-product decoding algorithm for LDPC codes.

Application of Low-density Parity-check(LDPC) codes and orthogonal frequency division multiplexing(OFDM) modulation technology were studied in the image transmission,and the effect of three kinds of different LDPC codes and OFDM modulation technology on the image transmission over wireless fading channel was studied and simulated.
