Comparison of (percent) DSRs for secondary message recovery for 5G polar and LDPC codes as a function of the eccentricity parameter obtained for a capture distance D = 12 in.
Source publication
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 th...

... reasonable (see Fig. 3) range [0.3, 0.7], the 5G polar codes consistently offered a better performance than the 5G LDPC codes. Specifically, either both codes had a DSR of 100% or 6 Parameter choices and implementation details are available in Appendix D. 0% or the polar codes had a higher DSR. A sample result over 10 5 simulations is shown in Fig. 4 for a typical barcode capture distance D = 12 in. and ∈ {0.3, 0.4, . . . , 0.7}, where the performance advantage of the polar codes can be seen, an advantage that was validated for different distances and eccentricity values in additional simulations. Hence, for the final optimized DMQR code design, we use 5G polar codes to ...
