Software defined radio layer for IR-UWB systems in Wireless Sensor Network context

This paper addresses the radio interface problematic for MANET (mobile ad-hoc network) applications. Here we propose to study the radio reconfigurability in order to provide a unique physical layer which is able to deal with all MANET applications. For implementing this reconfigurable physical layer, we propose to use Impulse Radio Ultra WideBand (IR- UWB). This paper presents also our two level design approach for obtaining our reconfigurable IR-UWB receiver on FPGA (field programmable gate array).
