Research on alleviating nonlinear problem by data feature extraction and fusion based on DFT-spread
EURASIP Journal on Advances in Signal Processing, 2023 Coherent optical orthogonal frequency division multiplexing (CO-OFDM) system is susceptible to nonlinear effects because of its intrinsic high peak-to-average ratio (PAPR). In this paper, two methods based on discrete Fourier transform spread (DFT-S) are

Electronic Notes in Theoretical Computer Science, 2009 AbstractBy imposing three semantic constraints on the π-calculus equipped with delayed input, we obtain a variant of the π-calculus. We prove that Hennessy and Riely's distributed π-calculus can be encoded into this new model, satisfying a full abstraction theorem, which means that one-dimensional mobility can be characterized by communication. We also
