Extented Reconfigurable Linear FeedBack Shift Register Operators for Software Defined Radio

Abstract : The expansion of Cognitive Radio (CR) was first impacted by the advent of Software Defined Radio (SDR). SDR provides the reconfigurability needed to switch from one standard to another. In this context and because it will reduce the size of the software to be downloaded, parameterization is an active research topic and appears as a keystone of SDR. Thereby, this paper points out an Extended Reconfigurable Linear Feedback Shift Register Based (ER-LFSR) structure, which can realizes several front rank operations of multi mode CR transceivers. Focused on OFDMbased Air Interfaces, the selected approach was to define a range of operations applying like-looking structures. In so doing, we specify two parameterizable structures to fulfill functions such as Pseudo Random Sequence Generators, Scrambling, Convolutive Coding, Cyclic coding, Reed-Solomon Coding or Reed-Solomon decoding.
