چکیده
The discrete polynomial transform (DPT) has been introduced recently as a computationally efficient algorithm for estimating the phase parameters of constant-amplitude polynomial phase signals. In this correspondence, we present a modification of the DPT, which improves the estimation accuracy. We show by a perturbation analysis that the mean-squared error of the estimates is reduced when the order of the polynomial is three or greater.

متن کاملStabilization of 2-D Recursive Digital Filters by the DHT Method - Circuits and Systems II: Analog and Digital Signal Processing, IEEE Transactions on
In this paper, we discuss the discrete Hilbert transform (DHT) method of stabilizing unstable two-dimensional (2-D) recursive digital filters originally proposed by Read and Treitel. We show that even in the one-dimensional case, the DHT method may yield an unstable polynomial when the given unstable polynomial has zeros on the unit circle. This is the case in the example presented by Read and ...
متن کاملOptimal approximation of uniformly rotated images: relationship between Karhunen-Loeve expansion and discrete cosine transform
We present the concept that for uniformly rotated images, the optimal approximation of the images can be obtained by computing the basis vectors for the discrete cosine transform (DCT) of the original image in polar coordinates, and that the images can be represented as linear combinations of the basis vectors.
متن کاملQuadrature prefilters for the discrete wavelet transform
Discrepancies between the Discrete Wavelet Transform and the coefficients of the Wavelet Series are known to be reducible by initialization of input data. Prefilters based on Lagrange interpolants are derived here for biorthogonal compact support wavelet systems, providing exact subspace projection in cases of local polynomial smoothness. The resulting convergence acceleration in a non-polynomi...
متن کاملA Maximum Likelihood Digital Receiver Using Coordinate Ascent And The Discrete Wavelet Transform - Signal Processing, IEEE Transactions on
In this paper, a maximum likelihood (ML) method is presented for joint estimation of amplitude, phase, time delay, and data symbols in a single-user direct-sequence spreadspectrum communication system. Since maximization of the likelihood function is analytically intractable, a novel coordinate ascent algorithm is used to obtain sequential updates of the data symbols and all unknown nuisance pa...
