碩士 === 國立中央大學 === 資訊及電子工程研究所 === 82 === To further increase the storage densities and reliability that systems using run-length limited (RLL) coding and peak detection (PD) can achieve, a more advanced technique on signal processing consisting of partial-response (PR) channel in combination with maximum-likelihood sequence detection (MLSD) is referred to as the PRML channel. Design a PRML system, the channel should be precisely characterized, and then the channel can be equalized and deteceed correctly. The nonlinear effects in high recording density should be compensated to improve the system performance.
