摘要
针对全息存储器具有大容量、高速率的工作特点,为了减少全息存储系统中各种噪声对数据的干扰,在设计通道时,采用了交错编码二值差分调制编码以及RS编码,有效降低了数据的误码率,使系统的误码率保持在10-12～10-13之间,满足了整个全息存储系统的工作要求。
According to the characteristics of holographic storage channel's mass capacity and high data transfer rate,and in order to overcome the hazards caused by the noise in the system,this paper adopts the cyclically shift interleaving codes,binary differential codes and the reedsolomond codes when designing the transferchannel,which can decrease the data error rate effectively,and keep the error rate between10 -12 and 10 -13 ,meeting the requirement of the whole holographic storage system.
