摘要

Cheng(博士论文,CIT, Pasadena, California, 1997)介绍了一类称为低密度发生器矩阵(LDGM)的线性码,并研究了其在无记忆加性高斯白噪声(AWGN)信道上的性能。本文研究了它在垂直磁记录通道上的性能。研究结果表明,某些ldgm码的误码率(BER)性能与相同速率的低密度奇偶校验码(LDPC)性能相当。

Performance of low-density generator matrix codes on perpendicular recording channels
Cheng (Doctoral Dissertation, CIT, Pasadena, California, 1997) introduced a class of linear codes called low-density generator matrix (LDGM) codes and studied its performance on a memoryless additive white Gaussian noise (AWGN) channel. In this paper, we study its performance on perpendicular magnetic recording channels. The results shown in this paper indicate that the bit-error rate (BER) performance of some LDGM-codes is comparable to that of low-density parity check (LDPC) codes of the same rate.
