Linear Convolution Using Skew-Cyclic Convolutions

IEEE Signal Processing Letters, 2007
It is shown that the linear convolution required in block filtering can be decomposed into a sum of skew-cyclic convolutions. Such convolutions can be realized efficiently with half-length complex transforms when the signals are real. This method results in computational savings over the traditional overlap-add and overlap-save algorithms.

A general analysis of cyclic block transmultiplexers with cyclic convolution

2015 IEEE 16th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2015
In this paper we investigate the class of cyclic block transmultiplexers (TMUXs). The perfect reconstruction (PR) conditions of their prototype function are derived both in time and frequency domain. A duality theorem is provided showing the connection between each PR solution in the frequency domain with its dual in time domain.

Improving accuracy in FFT-based cyclic convolution

2013 IEEE 56th International Midwest Symposium on Circuits and Systems (MWSCAS), 2013
When speed considerations are critical, FFT-based implementations of cyclic convolution need to be considered. Unfortunately, such FFT-based implementations of purely integer cyclic convolution can be affected by floating point round-off errors potentially leading to an incorrect integer result.

Cyclic Convolutional Codes over Separable Extensions

2015
We show that, under mild conditions of separability, an ideal code, as defined in Lopez-Permouth and Szabo (J Pure Appl Algebra 217(5):958–972, 2013), is a direct summand of an Ore extension and, consequently, it is generated by an idempotent element. We also design an algorithm for computing one of these idempotents.

On the structure of convolutional and cyclic convolutional codes

IEEE Transactions on Information Theory, 1979
Algebraic convolutional coding theory is considered. It is shown that any convolutional code has a canonical direct decomposition into subcodes and that this decomposition leads in a natural way to a minimal encoder. Considering cyclic convolutional codes, as defined by Piret, an easy application of the general theory yields a canonical direct ...

Discrete Wavelet Transform Basedon Cyclic Convolutions

IEEE Transactions on Signal Processing, 2004
A filterbank in which cyclic convolutions are used in place of linear convolutions will be referred to as a cyclic convolution filterbank (CCFB). A dyadic tree-structured CCFB can be used to perform a discrete wavelet transform suitable for coding based on symmetric extension methods.

Efficient reconfigurable architectures of generic cyclic convolution

2011 IEEE 15th International Symposium on Consumer Electronics (ISCE), 2011
This paper presents the design and implementation of a generic cyclic convolution architecture for imaging applications on field programmable gate array (FPGA). Two main architectures are implemented. A parallel architecture using distributed arithmetic (DA) and a sequential implementation using FPGA digital signal processor (DSP) resources were ...
