An Adaptive Compressed Sensing Method in Speech
نویسندگان
چکیده
The application of an adaptive compressive sensing method in the speech signal processing is proposed in this paper. First, the threshold of wavelet transform is used to preprocess the speech signal. Then, according to the parameters of the speech frame, each frame is adaptively assigned a measurement number. Finally, the measurement matrix is used to reconstruct the speech signal. Experimental results show that the proposed method can improve the SNR in the speech signal reconstruction and is of high robustness in different noise intensity

Compressed Sensing Adaptive Speech Characteristics Research
The sparsity of the speech signals is utilized in the DCT domain. According to the characteristics of the voice which may be separated into voiceless and voiced one, an adaptive measurement speech recovery method is proposed in this paper based on compressed sensing. First, the observed points are distributed based on the voicing energy ratio which the entire speech segment occupies. Then the s...
متن کاملSpeech Signal Compressed Sensing Based on K- Svd Adaptive Dictionary
This paper proposes a novel and successful method for speech signal compressed sensing based on KSingular Value Decomposition (K-SVD) algorithm. K-SVD is an iterative method that alternates between sparse representation of the train samples based on the current dictionary and a process of updating the dictionary atoms to better fit the speech data. The presented K-SVD algorithm is applied here ...
متن کاملStudy on adaptive compressed sensing & reconstruction of quantized speech signals
Compressed sensing (CS) is a rising focus in recent years for its simultaneous sampling and compression of sparse signals. Speech signals can be considered approximately sparse or compressible in some domains for natural characteristics. Thus, it has great prospect to apply compressed sensing to speech signals. This paper is involved in three aspects. Firstly, the sparsity and sparsifying matri...
متن کاملAccelerating Magnetic Resonance Imaging through Compressed Sensing Theory in the Direction space-k
Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...
متن کاملIterative methods for random sampling and compressed sensing recovery
In this paper, two methods are proposed which address the random sampling and compressed sensing recovery problems. The proposed random sampling recovery method is the Iterative Method with Adaptive Thresholding and Interpolation (IMATI). Simulation results indicate that the proposed method outperforms existing random sampling recovery methods such as Iterative Method with Adaptive Thresholding...
