DOI: 10.1109/lsp.2019.2922510
Abstract: A qualitative analysis to the output signal-to-noise ratio (SNR) optimization modeling and solving of Wigner distribution in linear canonical transform (LCT) domains is introduced. Within the well-established output SNR optimization model analysis framework, the strategies… read more here.
