It has lower bit error rate than other linear block codes and convolve codes over Gaussian noise channel,also it has good structures for ASIC implementation. QC-LDPC codes has a good application foreground in digital communications domain.
它不仅在高斯白噪声信道下具有和低密度奇偶校验码(LDPC码)一样优于其他线性分组码以及卷积码的低误码率(BER)性能,而且具有更利用集成电路硬件实现的结构,在新一代的通信领域具有广泛的应用前景。
