A Modular 1D-CNN Architecture for Real-time Digital Pre-distortion
Udara De Silva, Toshiaki Koike-Akino, Rui Ma +2
This study reports a novel hardware-friendly modular architecture for implementing one dimensional convolutional neural network (1D-CNN) digital predistortion (DPD) technique to li…
DNN-assisted optical geometric constellation shaped PSK modulation for PAM4-to-QPSK format conversion gateway node
Takahiro Kodama, Toshiaki Koike-Akino, David S. Millar +2
An optical gateway to convert four-level pulse amplitude modulation to quadrature phase shift keying modulation format having shaping gain was proposed for flexible intensity to ph…
FDTD-Based Diffuse Scattering and Transmission Models for Ray-Tracing of Millimeter-Wave Communication Systems
Stefanos Bakirtzis, Takahiro Hashimoto, Costas D. Sarris
At millimeter-wave frequencies, diffuse scattering from rough surfaces is an important propagation mechanism. Including this mechanism in radio propagation modeling tools,such as r…
On the Performance under Hard and Soft Bitwise Mismatched-Decoding
Tsuyoshi Yoshida, Mikael Mazur, Jochen Schröder +2
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 emp…
Performance Monitoring for Live Systems with Soft FEC and Multilevel Modulation
Tsuyoshi Yoshida, Mikael Mazur, Jochen Schröder +2
Performance monitoring is an essential function for margin measurements in live systems. Historically, system budgets have been described by the Q-factor converted from the bit err…
Post-FEC BER Benchmarking for Bit-Interleaved Coded Modulation with Probabilistic Shaping
Tsuyoshi Yoshida, Alex Alvarado, Magnus Karlsson +1
Accurate performance benchmarking after forward error correction (FEC) decoding is essential for system design in optical fiber communications. Generalized mutual information (GMI)…
