  • Abstract
    We propose a new two-dimensional (2D) modulation code for holographic data storage (HDS) systems. This code has a code rate of 3/4 and is called 6:8 variable-weight (VW) modulation code. Simulation results show that the 6:8 VW modulation code achieves a bit-error-rate (BER) of 10-3 with a coding gain of 5 dB and it outperforms the conventional balanced codes. In addition, we propose a modified decoding process, called two-step correlation, to further reduce the decoder complexity.
