采用Log-BP算法的LDPC码译码仿真程序，给出了不同信噪比下误码率和误包率的统计图，用matlab和C（c-mex）程序分别编写，有详细说明和注释。-The use of Log-BP decoding algorithm for LDPC code simulation program is given a different signal to noise ratio and bit error rate under the packet error rate of the statistical map, using matlab and C (c-mex) procedures, respectively, to prepare, has a detailed description and notes .

OFDM的一种频分复用方案。把频谱分成两个部分，一部分频谱用同频复用，一部分频谱采用复用因子为3，这就是reuse partitioning,或者叫部分频率复用技术（Fractional Frequency Reuse)。频率复用因子表示一个频率复用簇当中的频点的数量。复用因子越大，表示复用距离越大。代码对FFR进行了仿真，适合初学者。

此代码是用于DVB系统的信道编码模块，采用（204，188）编码方式，编码后前188个字节是信息位，后16个字节为冗余位。思绪仿真后，通过验证。-This code is used for DVB systems channel coding module (204,188) encoding, after encoding the previous 188 bytes of information, and after the 16-bit byte for redundancy. Simulation thoughts through authentication.
