Signal processing with CCDs

1974 IEEE International Solid-State Circuits Conference. Digest of Technical Papers, 1974

CCD signal processing is offering new methods for accomplishing many radar, communications and other signal sorting and analysis tasks at significantly lower cost than present digital techniques. The problem of discerning the appropriate device design for specific applications will be probed.


Fast n-D fourier-heisenberg transforms<sup>1</sup>

2000 10th European Signal Processing Conference, 2000

We develop fast Fourier-Heisenberg number theoretical transforms on discrete 1-D and n-D Heisenberg groups (H[3, GF(p), GF(p)] and H[n + 2, GFn(p), GFn(p)]) and over an arbitrary commutative ring K, where GF(p) is the Galois field, p = qmand g is a prime.

This correspondence explores the existence of convolution theorem for linear transformations under a variety of different assumptions. There are eight convolution theorems, all Fourier-related with only N operations in the transform domain and no ordering constraints on the convolution components in the result. They include circular convolutions and correlations.

Former known expressions for Chrestenson spectra can be obtained from the polynomial spectra by a simple modulo reduction. The coefficients of the spectral polynomials give exact information on the correlation ...

  • Fast computation of the discrete Hartley transform

    Two approaches to the computation of the discrete Hartley transform (DHT) are proposed. The first approach is based on computing a prime length DHT using a radix-2 number-theoretic transform. The number of multiplications required in this method is equal to N-1, which is less than the number of multiplications required for direct computation of the DHT using radix-2 or split radix algorithms. In the second approach, short-term transforms are implemented with rotations replacing multiplications. The availability of VLSI cordic processors implementing circular rotation makes this approach an interesting alternative to the realization of the transform.<<ETX>>

  • New formulation of fast discrete Hartley transform with the minimum number of multiplications

    A simple algorithm is proposed to realize a one-dimensional discrete Hartley transform (DHT) with sequence lengths equal to 2/sup m/. This algorithm achieves the same multiplicative complexity as Malvar's algorithm (1987, 1988) which requires the least number of multiplications reported in the literature. However, the approach gives the advantage of requiring a smaller number of additions compared with the number required in Malvar's algorithm.<<ETX>>

  • High speed 2D hexagonal convolution by polynomial transform

    The inherent nonseparable difficulty in 2D hexagonal sampled data can be overcome by choosing suitable periodicity and sampling basis, this will turn the original hexagonal data into very simple separable parallelograms, and then the rectangular polynomial transforms can be used to efficiently calculate 2D hexagonal convolutions; This algorithm is much faster than the hexagonal discrete Fourier transform method.

  • Digital all-pass filter design through discrete Hilbert transform

    A simple method for the design of a digital all-pass filter, satisfying the given group delay specification, is presented. The design is based on the discrete Hilbert transform relation, relating the log-magnitude and phase of the Fourier transform of the minimum phase signal. The transfer function of an all-pass filter is completely determined by the coefficients of the denominator polynomial. For the filter to be stable, the denominator polynomial must be minimum phase. From the given group delay specification, the phase corresponding to the pole part of the desired filter is first determined. The magnitude spectrum corresponding to the pole part of the desired filter is obtained from the above phase through the discrete Hilbert transform relation. The method needs just four fast Fourier transform operations. There is no restriction on the order of the filter, and the number of filter coefficients can be selected after the final design, depending on the accuracy desired. The procedure is illustrated through design examples.<<ETX>>

  • Efficient computation of the DFT of a 2N - point real sequence using FFT with CORDIC based butterflies

    In this paper, an efficient method for computation of the DFT of a 2N - point real sequence by using DIT FFT with CORDIC based butterflies is presented. Most of the real world applications use long real valued sequences. By using FFT with CORDIC based butterflies, the space required on ROM and also the time required to perform the operation can be reduced. Further, to calculate the 2N - point DFT, by using one N-point DFT involving complex valued data, efficiency is almost doubled.
