摘　　要：多波长光盘存储是增加存储密度的有效手段之一。针对多波长光盘信道中引入的波长间串扰,将序列检测技术扩展到多维,提出一种多波长部分响应最大似然MPRML(Multi-wavelength PRML)检测方法。以FPGA为核心设计了硬件仿真验证平台,可以对上述检测方法实现芯片级的算法验证。Muti-wavelength optical storage is one of the effective potential techniques to improve the storage density. A Multi-wavelength partial response maximum likelihood(MPRML) detection method is put forward, in order to reduce the inter wavelength interference(IWI). A hardware platform based on FPGA is also been developed to provide the chip level verification for the detection algorithm.
