In bit-patterned magnetic recording (BPMR), intersymbol interference (ISI) and inter-track interference (ITI) become a major impairment due to small bit and track pitches. One way to alleviate ISI and ITI is to encode the data sequence before recording. In general, two-dimensional (2D) coding scheme requires many redundant bits, thus lowering the code rate.(More)
In this paper, we studied the performance of the iterated Viterbi detection methods using the multi-track multi-head processing for a bit patterned media (BPM) channel with a two-dimensional interference consisting of inter-symbol interference (ISI) and inter-track interference (ITI). In each method, three Viterbi detectors are employed to process the three(More)
Due to bits being recorded at ultra-high density, a bit-patterned media recording (BPMR) system is faced with two-dimensional (2D) interference, namely inter-symbol interference (ISI) and inter-track interference (ITI), which degrades the overall performance of a recording system. One solution to avoid the 2D interference effect is to apply a modulation(More)
To forecast the weather accurately, meteorologists need the meteorological data from wireless sensor devices which are installed in different geographical areas besides from satellites. Nowadays, cloud computing technology can provide data storage and data processing tasks for the big meteorological data from numerous sensors. However, wireless sensors have(More)
In this paper, we compare the performance of the reduced complexity 2-D detection methods: Graph-based detection and Viterbi-based detection for the 2-D interference bit patterned media channels at various areal densities. In the graph-based detection, the complexity is reduced by ignoring the ITI from the cornered islands in designing the factor graph. In(More)
