This paper considers iterative detection and decoding on the concatenatedcommunication channel consisting of a two-dimensional magnetic recording (TDMR)channel modeled by the four-grain rectangular discrete grain model (DGM)proposed by Kavcic et. al., followed by a two-dimensional intersymbolinterference (2D-ISI) channel modeled by linear convolution of the DGM model'soutput with a finite-extent 2D blurring mask followed by addition of whiteGaussian noise. An iterative detection and decoding scheme combines TDMRdetection, 2D-ISI detection, and soft-in/soft-out (SISO) channel decoding in astructure with two iteration loops. In the first loop, the 2D-ISI channeldetector exchanges log-likelihood ratios (LLRs) with the TDMR detector. In thesecond loop, the TDMR detector exchanges LLRs with a serially concatenatedconvolutional code (SCCC) decoder. Simulation results for the concatenated TDMRand 2 x 2 averaging mask ISI channel with 10 dB SNR show that densities of 0.48user bits per grain and above can be achieved, corresponding to an arealdensity of about 9.6 Terabits per square inch, over the entire range of grainprobabilities in the TDMR model.
