Description: Turbo码，LDPC码（低密度奇偶校验码）均具有接近Shannon限的性能，
是目前便译码研究的热点。Turbo码在低信噪比情况下的性能优于其它各种编码
方式。而LDPC码的描述简单，具有较大的灵活性，当码长足够长时具有比Turbo
码更为良好的性能，其译码复杂度低于Turbo码。-Turbo code, LDPC code (LDPC) all have close to Shannon limit performance, it is the firm' s research focus. Turbo codes at low SNR is superior to other kinds of encoding. The simple description of LDPC codes with greater flexibility, when code length is long enough, have a much more favorable than the Turbo code performance, its decoding complexity than Turbo codes.

Description: 低密度奇偶校验码(简称LDPC码)是目前距离香农限最近的一种线性纠错码，它的直接编码运算量较大，通常具有码长的二次方复杂度．为此，利用有效的校验矩阵，来降低编码的复杂度，同时研究利用大规模集成电路实现LDPC码的编码．在ISE 8．2软件平台上采用基于FPGA的Verilog HDL语言实现了有效的编码过程，为LDPC码的硬件实现和实际应用提供了依据-Abstract：Low．density parity·check code(LDPC code)is a kind of linear eror·correcting code nearest to Shannon Limit．For LDPC
cod e，the computational overhead for direct encoding operations is large，as the complexity of encod ing is the square of the length of
codeword．Hence，this paper reduces the complexity of coding by using effective parity—check matrix，and realizes the encoding device
for LDPC code by use of large·scale integrated circuits．The effective encoding process based on FPGA with Verilog HDL language is
implemented on ISE 8．2 software platform ，providing a feasible basis for hardware implementation an d practical application of LDPC
code．
