Design Simulation of IEEE 802.11a Orthogonal Frequency Division Multiplexing (OFDM) Modem

open access: yesFES Journal of Engineering Sciences, 2011
This work is concerned with the design, software implementation considerations and performance evaluation of an 802.11a WLAN modem at base band level. The function of each block in transmitter is completely specified in the standard. But the receiver is not fully specified. Only the broad functionalities and the performance requirements are specified.

Nonlinear Distortion Equalization in Multi‐Span Optical Links Via a Feed‐Forward Photonic Neural Network

open access: yesLaser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.
A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.
