Performance of Concatenated 2D MAP for Multi-track Signal Detection

Mohammed Dikko Almustapha, Mahmoud Tukur Kabir, Hassan Abdulkarim.


Abstract
A low complexity two-dimensional (2D) detection technique for multi-track two-dimensional magnetic recording (TDMR) channel with shingled magnetic recording (SMR) media was presented in this paper. The technique involves the use of serially concatenated 2D maximum a posteriori (MAP) and a regular MAP detector for multi-track joint detection of a 2D signal. 2D MAP detector was applied in the along-track direction to cancel the inter-symbol interference while the regular MAP detector was used across-tracks for inter-track interference cancellation. The results show that the serially concatenated 2D MAP with regular MAP detector has less detection complexity as compared to full 2D detector when implemented for joint signal detection on an 8-track SMR media.

Key words: 2D detection, Two-dimensional magnetic recording (TDMR), Bahl Cocke Jelinek Raviv (BCJR) detector, Equalization, Maximum a-posteriori (MAP) decoding, Shingled magnetic recording (SMR). Inter-symbol interference (ISI), inter-track interference (ITI).
