Summary:
Two-dimensional (2-D) interference channel with inter-symbol interference (ISI) and inter-track interference (ITI) can degrade the performance of the read channel in bit patterned media recording (BPMR) system. In this work, we propose the method to improved graph-based (GB) detector. The factor graph applies to clusters in the cluster 2ﾃ・ channel matrix on 2-D interference channel to the GB detector. The simulation results show the performance of the proposed GB detector method with the conventional GB detector and multi-SOVA (64s) detector achieve the gains of about 0.8 and 1.0 dB at bit error rate equal 10-4, in the BPMR system with media noise at areal density 2 Tbits/in2.
