A Reconfigurable Linear FeedBack Shift Register Operator for Software Defined Radio Terminal

Abstract : Software Radio (SWR) is a keystone of Cognitive Radio (CR), mainly because it supplies the reconfigurability required to switch from one standard to another. In the SWR context, parameterization is an approach to lessen the size of the software to be downloaded. This paper is dedicated to a Reconfigurable Linear Feedback Shift Register Based Operator, which can carries out several front rank operations of multi mode CR transceivers. Focused on OFDM based Air Interfaces, the selected approach was to define a range of operations applying like-looking structures. In so doing, we point out a Reconfigurable LFSR-Based Operator, which carries through Pseudo Random Sequence Generators, Scrambling, Convolutive Coding, Cyclic coding, Reed-Solomon Coding or Reed-Solomon decoding. We compare the implementation of such an operator with classical approaches.
