    In the above-mentioned paper it was shown how two-dimensional convolutions of arrays of size μn by μn could be calculated by means of number theoretic transforms of length n by n. Some improvements can be made in this algorithm in the sense that the number of general multiplications can be reduced. Systematic techniques to accomplish this reduction are presented in this comment. View full abstract»

    The implementation of 2-D digital filters using logarithmic number systems (LNS's) is discussed in detail. The properties of such systems are derived with reference to an iterative rounding scheme, which allows increasing the accuracy of the filter coefficient representation by using more than one power of the base a. The optimization of the base is proposed as an efficient tool for the design of ... View full abstract»

    A procedure for the efficient numerical evaluation of the Hankel and Abel transforms is proposed. The Abel transform is reduced to a convolution which is evaluated in part analytically and in part with an FFT. The Hankel transform is obtained by following the Abel transform with an FFT.

    A new family of nonlinear digital convolution filters is described having unusual and valuable properties. The response is constant phase over the entire input frequency range and, in some forms, no signal whatsoever is passed beyond the cutoff frequency and side-lobes are identically zero. By simply iterating the transform upon which a Ξ-filter is based without changing the size of the convo... View full abstract»

    Proposed by Thompson in [1] was a technique for adaptive spectral estimation, particularly suited for tracking narrow-band signals in broad-band noise. This technique represented a data-adaptive variation of the block-oriented Pisarenko analysis technique. The algorithm departs from similar adaptive approaches based on linear prediction in that its estimate of line frequency is unbiased with the l... View full abstract»

    Using independent samples from two stationary Gaussian processes, second-order statistics are examined for the following three correlation estimators: 1) the direct estimator, 2) a "hybrid-sign" estimator, and 3) the polarity coincidence estimator. In most cases, increasing the number of samples by a factor of two or three allows one to use the simple polarity coincidence estimator with the same a... View full abstract»

    It is demonstrated that for applications in which adaptive cancellation of sinusoids, rather than enhancement, is desired, the effect of gradient noise is negligible when operating within the stability range of the filter. View full abstract»

    In this paper, K-cyclic frequency domain symmetry conditions for N-dimensional sampled signals are introduced. It is shown that these frequency domain symmetry conditions result in certain interrelationships between the sample values. A theorem is given that specifies these interrelationships. Several interesting properties of K-cyclic symmetries are discussed. Also, a systematic approach is given... View full abstract»

    In this paper, we present new algorithms for the calculation of convolutions by means of number theoretic transforms over modulo rings. Not only are these algorithms more efficient than currently used methods, but they are also very flexible. Indeed, using special algorithms for short convolutions allows trading computational efficiency for structural simplicity. View full abstract»

  • Design of IIR/FIR filters using a frequency domain bootstrapping technique and LPC methods

    Cited by:  Papers (10)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (784 KB)

    A technique is described for designing IIR/FIR digital filters which are specified by the number of poles and zeros, the sampling frequency, and a magnitude response versus frequency. The iterative technique to carry out the design bootstraps back and forth between the IIR (all pole) section and FIR (all zero) section, updating the design each time in the frequency domain using the data from the p...

    The sensitivity of interpolation of the pth derivative of a band-limited signal directly from the signal's samples in the presence of additive stationary noise is considered. Oversampling and filtering generally decrease the interpolation noise level when the data noise is not band-limited. A lower bound on the interpolation noise level can be approached arbitrarily closely by increasing the sampl... View full abstract»

    A class of completely-pipelined VLSI architectures is defined. Two topologies are then described: leaf-connected trees and mesh-connected trees. The leaf-connected tree structure is used to construct a completely-pipelined bit-serial multiplier and a completely-pipelined word-serial, bit-serial convolver. The mesh-connected tree structure is used to implement completely-pipelined bit-parallel mult... View full abstract»

    An analysis is presented for the steady-state response of a delay-constrained adaptive linear predictor filter to a sinusoid in white noise. Expressions are derived for the steady-state adaptive weights, frequency response, and line suppression. A useful bound is also derived for the worst-case output signal-to-noise ratio as a function of normalized frequency and the order of the filter. View full abstract»

    Recognition of connected words can be performed by segmenting the word string automatically into single-word components which are then classified by a single-word recognition system. We propose and investigate a speaker-independent segmentation procedure which is based completely on statistical principles.

    Bias and variance equations are presented for two-dimensional location estimators of a nonmoving point source of radiation in an isotropic, stationary random medium. The estimators are calculated from spatially correlated angle-of-arrival data which are collected simultaneously at two sensor positions, and assumed to consist of true (unbiased) source angles plus zero-mean angular noise with equal ...

    The paper presents a new method for the optimal design of minimum phase FIR filters. First, a constrained approximation procedure is used to obtain the magnitude function and the transmission zeros in the stopband(s). Next, the zeros of the transfer function inside the unit circle are calculated via a low-degree polynomial factorization. For low-pass filters, a straightforward exchange algorithm i...

    Two-dimensional IIR filters are designed using an error criterion consisting of the weighted sum of magnitude, phase, and stability errors, thereby extending the spectral factorization-based method to complex approximation. The weights are adjusted to effectively constrain stability while minimizing a weighted sum of frequency domain magnitude and phase errors. We use a derivative-free variant of ...

    In this paper, a signal is shown to be uniquely represented by the magnitude of its short-time Fourier transform (STFT) under mild restrictions on the signal and the analysis window of the STFT. Furthermore, various algorithms are developed which reconstruct signal from appropriate samples of the STFT magnitude. Several of the algorithms can also be used to obtain signal estimates from the process... View full abstract»

    The relative contribution by a noiselessly observed input signal to the power of a possibly disturbed observed stationary output signal from a linear system is expressed into signal spectral densities. Approximations of estimator statistics and derived confidence limits agree fairly well with simulation results for white signals. View full abstract»
