Reduced Complexity Detection in MIMO Systems with SC-FDE Modulations and Iterative DFE Receivers
Journal of Sensor and Actuator Networks, 2018 This paper considers a Multiple-Input Multiple-Output (MIMO) system with P transmitting and R receiving antennas and different overall noise characteristics on the different receiver antennas (e.g., due to nonlinear effects at the receiver side).

Roadmap on nonlinear optics–focus on Chinese research
JPhys Photonics, 2023 In nonlinear optical systems, the optical superposition principle breaks down. The system’s response (including electric polarization, current density, etc) is not proportional to the stimulus it receives. Over the past half century, nonlinear optics has

Photonic Microwave Filter With Steep Skirt Selectivity Based on Stimulated Brillouin Scattering
IEEE Photonics Journal, 2016 A method to enhance the filter slope of Brillouin-based photonic microwave filters is presented. This improvement is achieved by the combination of Brillouin gain and loss responses over phase-modulated signals.

Transient linear growth and nonlinear effects
, 2001 We study a simple model consisting of two coupled nonlinear ordinary differential equations to display the interplay between transient linear growth and nonlinear effects. Specifically, we seek to examine any possible links between the initial conditions
