Reduction of Symmetric Complex Filters

IEEE Transactions on Signal Processing, 2010
Due to their linear-phase property, symmetric filters are an interesting class of finite-impulse-response (FIR) filters. Moreover, symmetric FIR filters allow an efficient implementation. In this paper we extend the classical definition of Hermitian symmetry to a more general symmetry that is also applicable to complex filters.

Complexity reduction: A pragmatic approach

Systems Engineering, 2011
Abstract An increasing need for shared communication in disparate domains as well as the production of increasingly dynamic, large‐scale systems has always been at the heart of the practice of systems engineering. As a branch of general systems theory, systems engineering was developed to address practical considerations posed by ...

On the Reduction of Additive Complexity of Cyclotomic FFTs

IEEE Transactions on Communications, 2012
We investigate a property that we have found in many efficient bilinear cyclic convolutions in GF (2m). We show that this property can reduce the additive complexity of cyclotomic FFTs. We explain how it arises, and why the most common constructions of cyclic convolutions yield this beneficial feature.

Complexity Reduction: theory, metrics and applications

2007 IEEE International Conference on Research, Innovation and Vision for the Future, 2007
Generalized Galois lattices formalism for computing contextual categorization allows metrics to evaluate complexity and efficiency as well as methods for simplifying or complicating the external object at hand. Such methods are adapted for virtual environments and augmented reality devices for which it is simple to change the distribution of features ...
