中文说明：资源描述 LDPC译码的最小和算法（min-sum algorithm, MSA）在matlab中的实现。程序完整可用。 文件中包括了随机校验矩阵构造，随机信息生成，编码，噪声信道模拟，译码，记录等全部流程的程序。用户可以根据自身需求调整校验矩阵，信道错误率等参数，为了解LDPC码原理或进行试验带来方便。 每次运行后的结果还可以自动写入工作目录下minsumdata.xlsx文件，以备后期查阅结果，防止数据丢失。
English Description：
Application backgroundThe implementation of MSA LDPC (algorithm) in matlab. Complete program available.The paper includes a random check matrix construction, random information generation, encoding, noise channel simulation, decoding, recording, and other procedures. User can adjust the check matrix according to their own needs, channel error rate and other parameters, in order to understand the principle of LDPC code or to bring convenience. After each run, the results can also be automatically written to the working directory minsumdata.xlsx file, in order to prepare for the late access to the results, to prevent data loss.
