Practical Product Code Construction of Polar Codes
Carlo Condo, Valerio Bioglio, Hartmut Hafermann +1
In this paper, we study the connection between polar codes and product codes. Our analysis shows that the product of two polar codes is again a polar code, and we provide guideline…
Partially Ordered Statistics Demapping for Multi-Dimensional Modulation Formats
Djalal F. Bendimerad, Huijian Zhang, Ingmar Land +1
We propose a very low-complexity and high-performance algorithm for soft-demapping of multi-dimensional modulation formats. We assess its performance over the linear channel for fo…
Experimental Demonstration of Data Transmission Based on the Exact Inverse Periodic Nonlinear Fourier Transform
Jan-Willem Goossens, Yves Jaouën, Hartmut Hafermann
We design a two-dimensional signal constellation based on the exact periodic inverse nonlinear Fourier transform. Feasibility of continuous transmission with periodic signals is ex…
Increasing Achievable Information Rates via Geometric Shaping
Bin Chen, Chigo Okonkwo, Hartmut Hafermann +1
Achievable information rates are used as a metric to design novel modulation formats via geometric shaping. The proposed geometrically shaped 256-ary constellation achieves SNR gai…
Nonlinearity-tolerant 8D modulation formats by set-partitioning PDM-QPSK
D. F. Bendimerad, H. Hafermann, H. Zhang
We present two new nonlinearity tolerant modulation formats at spectral efficiencies lower than 4bits/4D-symbol, obtained using a simplified bit-to-symbol mapping approach to set-p…
Polarization-Division Multiplexing Based on the Nonlinear Fourier Transform
Jan-Willem Goossens, Mansoor I. Yousefi, Yves Jaouën +1
Polarization-division multiplexed (PDM) transmission based on the nonlinear Fourier transform (NFT) is proposed for optical fiber communication. The NFT algorithms are generalized…
