New Angles on the Multidimensional Intersymbol Interference (ISI) Problem

 

  •  Objective:

    • Invent new algorithms to reduce or eliminate the effects of 2D and 3D ISI in next generation optical disk and holographic storage systems.

  • Technologies:

    • Iterative 2D ISI equalization; lowdensity parity check (LDPC) coding; Markov random field (MRF) modeling.

  •  Uniqueness:

    • Best-performing 2D ISI equalizer published to date; only published algorithm to exploit MRF structure of 2D input data.

  • PIs: Benjamin Belzer and Krishnamoorthy Sivakumar

  • Sponsor: NSF; $426K, 2006-’09
