This paper proposes to use embedded data
to improve the intensity of high-frequency
information in the Fourier intensity
distribution, thereby improving noise
immunity. In simulation, the convergence
speed of BER (the bit error rate) is faster
under the same number of iterations.

A method for collinear non-interferometricphase retrieval holographic data storage
using a single reference pixel is proposed.
Increasing the intensity of the reference
beam can achieve phase retrieval using only
one reference pixel. As the intensity of thereference beam becomes stronger within acertain range, the number of iterations
gradually decreases.
