Classification of discrete signal

WebApr 12, 2024 · Identifying the modulation type of radio signals is challenging in both military and civilian applications such as radio monitoring and spectrum allocation. This has become more difficult as the number of signal types increases and the channel environment becomes more complex. Deep learning-based automatic modulation classification … WebApr 7, 2024 · In graph neural networks (GNNs), both node features and labels are examples of graph signals, a key notion in graph signal processing (GSP). While it is common in GSP to impose signal smoothness constraints in learning and estimation tasks, it is unclear how this can be done for discrete node labels. We bridge this gap by introducing the concept …

WebMar 4, 2024 · This article presents an efficient model for EEG classification by considering feature extraction and selection. Seven different types of common wavelets were tested in our research work. These are Discrete Meyer (dmey), Reverse biorthogonal (rbio), Biorthogonal (bior), Daubechies (db), Symlets (sym), Coiflets (coif), and Haar (Haar). Web2 Discrete Time Signals: Sampling and Transform A discrete time signal is denoted s(n) or s n, where n is an integer and the value of s can be real or complex. It comes from a sampling or discretization of a continuous signal s(t) with t = n∆, where ∆ > 0 is a discrete time step known as the sampling interval. A discrete signal is called ...
