N2 - The performance of an iterative decoding system is evaluated in shingled magnetic recording (SMR). The medium model is made by a discrete Voronoi model, and the 2-D sensitivity function of reader is used to obtain the reproducing waveform. As the sensitivity function extends to adjacent tracks, intertrack interference (ITI) deteriorates the signal detection system. In order to recover the intrinsic performance, it is required to reduce the influence of ITI to the system. Then, the ITI canceller is employed to combat ITI for the iterative decoding system, and the performance is evaluated by computer simulation. The results show that the introduction of ITI canceller improves the bit-error-rate performance in SMR system.
