主　　题：holographic data storage(HDS) phase retrieval embedded data high frequency 

摘      要：Embedded data are used to retrieve phases quicker with high accuracy in phase-modulated holographic data storage(HDS).We propose a method to design an embedded data distribution using iterations to enhance the intensity of the high-frequency signal in the Fourier *** proposed method increases the antinoise performance and signal-to-noise ratio(SNR)of the Fourier spectrum distribution,realizing a more efficient phase *** indicate that the bit error rate(BER)of this method can be reduced by a factor of one after 10 iterations.
