Modulation Decoding Based on K-Means Algorithm for Bit-Patterned Media Recording
Applied Sciences, 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).

Optimized Modulation and Coding for Dual Modulated QR Codes
IEEE Transactions on Image Processing, 2022 <p> We present optimized modulation and coding for the recently introduced dual modulated QR (DMQR) codes that extend traditional QR codes to carry additional secondary data in the orientation of elliptical dots that replace black modules in the barcode images. By dynamically adjusting the dot size, we realize gains in embedding strength for both

Coded modulation scheme employing turbo codes
Electronics Letters, 1995 The authors present a turbo coding scheme for bandwidth-efficient modulation that outperforms turbo coding with Gray mapping by employing Ungerboeck codes as component codes. The scheme can be decoded iteratively and achieves very good bit error rates at low signal to noise ratios after a small number of iterations. 8PSK is used as an example, although
