Cycle-Slip Rate Analysis of Blind Phase Search DSP Circuit Implementations
- 2020

Ingår i: 2020 Optical Fiber Communications Conference and Exhibition, OFC 2020 - Proceedings. - 9781943580712
-
Konferensbidrag (refereegranskat)abstract
- Using FPGA-accelerated simulations, we study the cycle-slip rate of 16QAM blind phase search implementations. While block averaging suffers from degraded BER when compared to sliding-window averaging, it results in lower cycle-slip rates and power dissipation.

ASIC Design Exploration for DSP and FEC of 400-Gbit/s Coherent Data-Center Interconnect Receivers
- 2020
-
Ingår i: 2020 Optical Fiber Communications Conference and Exhibition, OFC 2020 - Proceedings. - : Optical Society of America. - 9781943580712
-
Konferensbidrag (refereegranskat)abstract
- We perform exploratory ASIC design of key DSP and FEC units for 400-Gbit/s coherent data-center interconnect receivers. In 22-nm CMOS, the considered units together dissipate 5W, suggesting implementation feasibility in power-constrained form factors.

Ingår i: Conference on Optical Fiber Communication, Technical Digest Series. - 9781943580712 ; Part F174-OFC 2020
-
Konferensbidrag (refereegranskat)abstract
- We discuss the role of supervised, unsupervised and semi-supervised learning techniques in identification of optical network security breaches. The applicability, performance and challenges related to practical deployment of these techniques are examined.

Model-Based Machine Learning for Joint Digital Backpropagation and PMD Compensation
- 2020
-
Ingår i: Optical Fiber Communication Conference (OFC) 2020. - 9781943580712
-
Konferensbidrag (refereegranskat)abstract
- We propose a model-based machine-learning approach for polarization-multiplexed systems by parameterizing the split-step method for the Manakov-PMD equation. This approach performs hardware-friendly DBP and distributed PMD compensation with performance close to the PMD-free case. © 2020 OSA.

Transmission of 36-Gbaud PAM-8 Signal in IM/DD System using Pairwise-Distributed Probabilistic Amplitude Shaping
- 2020
-
Ingår i: 2020 Optical Fiber Communications Conference and Exhibition, OFC 2020 - Proceedings. - 2162-2701. - 9781943580712
-
Konferensbidrag (refereegranskat)abstract
- We experimentally demonstrate the transmission of 36-Gbaud probabilistically-shaped PAM-8 signal over 10-km link. The performance measured after FEC decoding and inverse distribution matcher shows that the receiver sensitivity is improved by >1 dB compared to uniform-distributed signals.

Improved Simulation Accuracy of the Split-Step Fourier Method
- 2020
-
Ingår i: Optical Fiber Communication Conference. - 9781943580712
-
Konferensbidrag (refereegranskat)abstract
- We investigate a modified split-step Fourier method (SSFM) by including low-pass filters in the linear steps. This method can simultaneously achieve a higher simulation accuracy and a slightly reduced complexity.

Multi-Channel Equalization for Comb-Based Systems

Ingår i: 2020 Optical Fiber Communications Conference and Exhibition, OFC 2020 - Proceedings. - 9781943580712
-
Konferensbidrag (refereegranskat)abstract
- We propose and demonstrate a frequency comb-enabled joint DSP. With joint processing, the required guard-bands decreases and the optimal roll-off factor increases, reducing penalties from non-ideal transceiver electronics while simultaneously increasing the spectral efficiency. © 2020 OSA.

On the Performance under Hard and Soft Bitwise Mismatched-Decoding

Ingår i: 2020 Optical Fiber Communications Conference and Exhibition, OFC 2020 - Proceedings. - 9781943580712
-
Konferensbidrag (refereegranskat)abstract
- We investigated a suitable auxiliary channel setting and the gap between Q-factors with hard and soft demapping. The system margin definition should be reconsidered for systems employing complex coded modulation with soft forward error correction.
