Promising Technique of Parameterization For Reconfigurable Radio, the Common Operators Technique: Fundamentals and Examples

Abstract

ISSN : 1939-8018 (Print) 1939-8115 (Online)In the field of Software Radio (SWR), parameterization studies have become a very important topic. This is mainly because parameterization will probably decrease the size of the software to be downloaded, and also because it will limit the reconfiguration time. In this paper, parameterization is considered as a digital radio design methodology. Two different techniques, namely common functions and common operators are considered. In this paper, the second view is developed and illustrated by two examples: the well known Fast Fourier Transform (FFT) and the proposed Reconfigurable Linear Feedback Shift Register (R-LFSR), derived from the classical Linear Feedback Shift Register (LFSR) structure

“…The common operator technique belongs to the parameterization techniques firstly proposed by Jondral et al (2002). The common operators' technique is discussed more extensively in Alaus et al (2008). A part of the theoretical approach of this technique is presented in Rodriguez et al (2007).…”

A technique for the identification of reconfigurable resources of flexible communication systems

“…For instance, G 1.5 and G 2.3 represents low-pass filters, which can be described by the Laplace Transfer Functions H 1 (s) = 9.42 * 10 6 9.42 * 10 6 +s and H 2 (s) = 4.4 * 10 6 4.4 * 10 6 +s . Their elementary node level HDFG+R representations are shown in Fig.…”

Versatile digital architecture for mobile terminal

“…Indeed, one optimization process of the architectural synthesis technique is the common operators (CO) or sharing functions (SF) technique which may reduce the implementation logic area for producing a optimized design suitable for embedded applications, was introduced in [2,3]. More precisely, in the common processing procedure of an architectural synthesis design based on reusing of the common tasks, a functional unit instance can be shared by more than one operation so that it occupies the smaller area for execution of several data-path parts corresponding to different data operation processing algorithms [3,6,7,34,35]. The common operators technique consists in identifying and extracting the parts of an application which is described in form of data-flow graph in order to implement by the synthesis architecture (shared on functional units).…”

“…The aim is to realize an optimal implementation that satisfies the constraints (real time, logic area, etc.). Therefore, the common operators or functions implementation approach can be useful in the particular case to design a generic implementation of multi standard communications [35].…”
