Modulation Decoding Based on K-Means Algorithm for Bit-Patterned Media Recording

, 2022
In bit-patterned media recording (BPMR) systems, the readback signal is affected by neighboring islands that are characterized by intersymbol interference (ISI) and intertrack interference (ITI).

Two-Dimensional 15/24 Non-Isolated Patterned Modulation Codes With Minimum Hamming Distance 3 in Bit-Patterned Media Recording

IEEE Access
Reducing the distance between magnetic islands is essential for increasing the areal density in bit-patterned media recording (BPMR). Consequently, significant two-dimensional (2D) interference emerges, encompassing inter-symbol interference (ISI) and ...
