Durağan olmayan çok bileşenli boğucu sinyaller için yeni bir uyarlanır karışma çıkarıcı analizi
Durak, L.; Arıkan, Orhan; Song, I. (IEEE, 2005)A novel adaptive short-time Fourier transform (STFT) implementation for the analysis of non-stationary multi-component jammer signals is introduced. The proposed time-frequency distribution is the fusion of optimum STFTs ... -
Efficient computation of joint fractional Fourier domain signal representation
Durak, L.; Özdemir, A. K.; Arıkan, Orhan (Optical Society of America, 2008)A joint fractional domain signal representation is proposed based on an intuitive understanding from a time-frequency distribution of signals that designates the joint time and frequency energy content. The joint fractional ... -
Generalization of time-frequency signal representations to joint fractional Fourier domains
Durak, L.; Özdemir, A. K.; Arıkan, Orhan; Song, I. (IEEE, 2005-09)The 2-D signal representations of variables rather than time and frequency have been proposed based on either Hermitian or unitary operators. As an alternative to the theoretical derivations based on operators, we propose ... -
A novel STFT implementation for the analysis of non-stationary jammer interference
Durak, L.; Arıkan, Orhan; Song, I. (IASTED, 2004)A novel adaptive short-time Fourier transform (STFT) implementation for the analysis of non-stationary multi-component jammer signals is introduced. The proposed time-frequency distribution is the fusion of optimum STFTs ... -
Short-time Fourier transform: two fundamental properties and an optimal implementation
Durak, L.; Arıkan, Orhan (IEEE, 2003)Shift and rotation invariance properties of linear time-frequency representations are investigated. It is shown that among all linear time-frequency representations, only the short-time Fourier transform (STFT) family with ...
