Architecture Reconfigurable pour un Equipement Radio Multistandard

Abstract : In the present day, the profusion of wireless communication standards leads to complex terminals able to manage a wide range of standards, which calls for multistandard terminals. In order to meet the requirement of such terminals, we propose a new Parameterization strategy to design a Recon_gurable Terminal. With this method, - The Common Operator Technique - Parameterization focuses on smaller building blocks that can be reused across many of the functions required by each standard. The Method leads up to higher scalability and recon_gurability at the expense of an extra scheduling to handle with. As a consequence, we propose a new architecture in Common Operator Bank (COB), which limits the scheduling issue though optimizing the hardware complexity. Three families of Common Operators are introduced, (LFSR, Treillis/Butter_ies, CORDIC). The _rst realizations obtained in COB are based on LFSR and CORDIC operators. Centered on a tri-standard terminal (3GPP LTE, IEEE802.11g and 802.16e), the implementation on a FPGA, Altera/Cyclone II results in a Logic Cells complexity decrease of 40%.
