نویسندگان
چکیده
A concept of the sub-band operator of multi-band wavelets is introduced, the theory of d-circular matrices is developed and the upper bound and the lower bound of the norm of the sub-band operator are obtained. Examples are provided to illustrate the results proposed in this paper.

Shift variance behavior for different sub - band coding systems , Biorthogonal , Orthogonal and Bspline wavelets
Sub-band coding has long been utilized and adopted in different compression, coding and reconstruction techniques in most signal processing applications. It has wide applications in communications, bit rate codec’s, sampling, and compression for images, videos and speech. However sub-band coding systems in general suffer from a certain amount of shift variance of the output reconstructed signal...
متن کاملAsymptotic Close to Optimal Resource Allocation in Centralized Multi-band Wireless Networks
This paper concerns sub-channel allocation in multi-user wireless networks with a view to increasing the network throughput. It is assumed there are some sub-channels to be equally divided among active links, such that the total sum rate increases, where it is assumed each link is subject to a maximum transmit power constraint. This problem is found to be a non-convex optimization problem and i...

Functionalized Multi-walled carbon nanotubes (f-MWCNTs) which are modified using nitric acid and sulfuric acid were evaluated to synthesize a uniform nanocomposite via application of TiO2. The f-MWCNTs-TiO2 nanocomposites have been produced via using the chemical simple two-step method. To characterize the structural analysis, scanning electron microscopy...
متن کاملWavelets, Approximation and Compression: A Review
In this paper, we briefly review the connection between subband coding, wavelet approximation and general cornpression problems. Wavelet or subband coding is successful in compression applications partly because of the good approximation properties of wavelets. First, we revisit some rate-distortion bounds for wavelet approximation of piecewise smooth functions. We contrast these results with r...
متن کاملMulti-Channel Sub-Band Speech Recognition
Two distinct fields of research into robust speech recognition are the use of microphone arrays for signal enhancement and the use of independent frequency sub-band models for robust recognition. In this article, we propose and investigate the integration of these two techniques on two different levels. First, a broad-band beamforming microphone array allows for natural integration with sub-ban...
