Versatile Time-Frequency Representations Realized by Convex Penalty on Magnitude Spectrogram
Keidai Arai, Koki Yamada, Kohei Yatabe
Sparse time-frequency (T-F) representations have been an important research topic for more than several decades. Among them, optimization-based methods (in particular, extensions o…
Sparse time-frequency representation via atomic norm minimization
Tsubasa Kusano, Kohei Yatabe, Yasuhiro Oikawa
Nonstationary signals are commonly analyzed and processed in the time-frequency (T-F) domain that is obtained by the discrete Gabor transform (DGT). The T-F representation obtained…
Designing nearly tight window for improving time-frequency masking
Tsubasa Kusano, Yoshiki Masuyama, Kohei Yatabe +1
Many audio signal processing methods are formulated in the time-frequency (T-F) domain which is obtained by the short-time Fourier transform (STFT). The properties of the STFT are…
