Spatial Quadrature Amplitude Modulation (SQAM) is a promising approach for increasing the storage density of holographic memory . We previously proposed a batch reading and decoding method that decodes individual SQAM signals from interference intensity distributions generated by multiple simultaneously reconstructed signals. In this study, a Multi-Layer Perceptron (MLP)- based neural network was developed to directly estimate the amplitude ratios and phase differences among multiplexed SQAM signals from interference intensity distributions. The proposed method was validated through numerical simulation.
