On the use of dynamic partial reconfiguration for multi-band/multi-standard software defined radio

Abstract

Reconfigurable system is an old term aims to combine fixed and variable computing structures. This term extends its power when it is applied with the Software Defined Radio (SDR) in the communications industry, where the physical layer is being adaptable to accommodate Multi-Standard Communication Systems. The FPGA is considered a best platform for the Reconfigurable Computing (RC) and SDR. This proposed work shows the advantages of using FPGA feature, Dynamic Partial Reconfiguration (DPR), in the implementation of SDR System that can switch among different communication standards such as 2G, 3G, LTE, and WIFI. The reconfiguration takes place dynamically on a part of the FPGA while the rest of the FPGA is functioning. The implementation is carried out on Xilinx Virtex 5 evaluation kit XUPV5-LX110T.
