Fast Reconstruction of SAR Images with Phase Error Using Sparse Representation

In the past years, a number of algorithms have been introduced for synthesis aperture radar (SAR) imaging. However, they all suffer from the same problem: The data size to process is considerably large. In recent years, compressive sensing and sparse representation of the signal in SAR has gained a significant research interest. This method offers the advantage of reducing the sampling rate, bu...

Speech Reconstruction from Binary Masked Spectrograms Using Vector Quantized Speaker Models

Several source separation techniques use binary masking on spectrograms to separate two or more speakers from each other. In this thesis, the possibilities for obtaining the best quality signal, reconstructed from masked spectrograms through vector quantized models of speakers, is investigated. The advantages and disadvantages of such an approach are examined. Additionally, the task of signal r...
