Enhanced Performance of Artificial-Neural-Network-Based Equalization for Short-Haul Fiber-Optic Communications [PDF]

Sensors, 2023
This work proposes an efficient and easy-to-implement single-layer artificial neural network (ANN)-based equalizer with improved compensation performance. The proposed equalizer is used for effectively mitigating the distortions induced in the short-haul

Accurate Characterization for Continuous-Time Linear Equalization in CMOS Optical Receivers

IEEE Access, 2022
Recently published CMOS optical receivers consist of a limited-bandwidth first-stage transimpedance amplifier (TIA) followed by an equalizer. Limiting the TIA’s bandwidth improves the gain and reduces the noise but introduces a significant inter ...

The intricate geometry of zero-determinant strategies underlying evolutionary adaptation from extortion to generosity

New Journal of Physics, 2022
The advent of zero-determinant (ZD) strategies has reshaped the study of reciprocity and cooperation in the iterated prisoner’s dilemma games. The ramification of ZD strategies has been demonstrated through their ability to unilaterally enforce a linear ...
