FIR to FIR Model Reduction with Linear Group Delay in Passband by SDP Optimization

Journal of Electrical and Computer Engineering, 2020
Filter model reduction is an important optimization method in digital signal processing. A method of FIR to FIR model reduction using SDP optimization is proposed in this paper. At first, we use SDP to design an original FIR filter.

Supervised Reciprocal Filter for OFDM Radar Signal Processing

IEEE Transactions on Aerospace and Electronic Systems, 2023
In this paper, we address the problem of the range-Doppler map evaluation in continuous wave radar exploiting OFDM signals. This stage is usually implemented by resorting to a suboptimal batches algorithm and a typical choice is to fragment the signal in batches with length equal to the OFDM symbol length and to apply at each batch an appropriate range

A nonlinear optoelectronic filter for electronic signal processing [PDF]

Scientific Reports, 2014
The conversion of electrical signals into modulated optical waves and back into electrical signals provides the capacity for low-loss radio-frequency (RF) signal transfer over optical fiber. Here, we show that the unique properties of this microwave-photonic link also enable the manipulation of RF signals beyond what is possible in conventional systems.
