BD系统中的信号重构技术

Signal reproduced techniques in BD system

伺服系统从媒体介质中恢复出二进制数据流的过程称为信号重构(Reproduced)。经典的光盘信号重构技术是峰值检测(Peak-Peak),该技术算法简单,容易实现,在DVD/CD播放系统中有着广泛应用。但是随着高清时代的到来。

For improving storage density of the optical disc,some key technologies are used in Blu-ray system.One of them is PRML.In the following,the application of PRML for Blu-ray system is introduced.Then,the process of signal reproduced is analyzed.At the end,method to calculate MLSE performance is given in this article.
