Abstract :
We study iterative decoding and equalization for information storage systems that have two-dimensional (2-D) intersymbol interference (ISI) during read-back. Four iterative schemes for 2-D equalization are introduced and evaluated. Two schemes are based on turbo equalization, the third on minimum mean squared error estimation, and the fourth on message passing on the combined graph of the channel ISI and the error correction code.
