Abstract:
We introduce novel irregular polar codes, which extend the regular polar coding by flexible polarization pruning. We experimentally demonstrate that the proposed polar codes outperform state-of the-art LDPC codes, while the computational complexity in encoding and decoding can be significantly reduced by at least 30% over the regular polar codes with a marginal performance improvement.

Research Areas: Communications, Electronic and Photonic Devices, Signal ProcessingBrief- Two papers from the Optical Communications team were presented at the 2017 European Conference on Optical Communication (ECOC) held in Gothenburg, Sweden in September 2017. The papers relate to enhanced error correction coding for coherent optical links and advanced precoding for optical data center networks. The invited paper studied irregular polar coding to reduce computational complexity, decoding latency, and bit error rate at the same time. In addition to two papers, the team member was invited to talk about constellation shaping as a workshop panelist.
