Robust Learning with Frequency Domain Regularization

CoRR, 2020
Convolution neural networks have achieved remarkable performance in many tasks of computing vision. However, CNN tends to bias to low frequency components. They prioritize capturing low frequency patterns which lead them fail when suffering from application scenario transformation.

B-spline neural network based single-carrier frequency domain equalisation for Hammerstein channels [PDF]

, 2014
A practical single-carrier (SC) block transmission with frequency domain equalisation (FDE) system can generally be modelled by the Hammerstein system that includes the nonlinear distortion effects of the high power amplifier (HPA) at transmitter.

Frequency-domain precoding for single carrier frequency-division multiple access [PDF]

, 2009
At present there is considerable interest in the use of single carrier frequency-division multiple access. This interest is justified by the inherent single carrier structure of the SC-FDMA scheme, which is more robust against phase noise and has a lower
