说明：  应用背景 低密度奇偶校验码（LDPC）是其中最好的执行前向纠错码的今天。特别是对无线通信系统，准循环（QC）LDPC码得到显著注意，因为它们的定期校验矩阵有利于成本效益和低功耗的硬件实现，并允许轻松地调整块长度和代码率。因此，QC-LDPC码中采用了大量的最近的无线通信标准，例如，IEEE 802.16e，DVB-S2，IEEE802.11n。 关键技术 软件包中包含一个模拟LDPC码的编码和解码中使用的IEEE 802.11n无线环境局域网标准。代码是用Matlab和包括一个灵活的Monte Carlo仿真环境，可以很容易地扩展其他的LDPC码代码；(Application background low density parity check (LDPC) codes are among the best performing forward error correction codes today. For wireless communication systems in particular, quasi cyclic (QC) LDPC codes have received significant attention because their periodic check matrix is beneficial to cost-effective and low-power hardware implementation, and allows easy adjustment of block length and code rate. Therefore, a large number of recent wireless communication standards are adopted in QC-LDPC codes, such as IEEE 802.16e, DVB-S2, ieee802.11n. The key technology package contains an IEEE 802.11n WLAN standard for analog LDPC coding and decoding. The code uses MATLAB and includes a flexible Monte Carlo simulation environment, which can easily extend other LDPC codes;)
