- 論文の詳細を見る
We present partial response maximum likelihood (PRML) detection with two-dimensional (2D) equalizer scheme and introduce 2D soft output Viterbi algorithm (SOVA) detection for holographic data storage (HDS) channel. We also propose the 2D PR target for the HDS channel varying the grade of blur. Simulation results show that the proposed schemes outperform the nearest neighbor detection.
