Abstract: Neural vocoders often struggle with aliasing in latent feature spaces, caused by time-domain nonlinear operations and resampling layers. Aliasing folds high-frequency components into the low ...
Abstract: Constant modulus algorithm (CMA) has been widely used in direction of arrival (DOA) estimation for constant modulus signals. However, CMA fails completely when dealing with array elements ...
For nearly forty years, a strange signal has been drifting through the North Pacific, making scientists scratch their heads. It comes in at 52 hertz, a pitch no known whale normally makes. The whale ...
Treat the CSI subcarrier-by-time matrix as a grayscale spectrogram image and apply CNN embedding to produce a 128-dimensional representation that preserves 2D spatial-frequency structure.
