Abstract

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 (IRUWB). This paper presents also our two level design approach for obtaining our reconfigurable IR-UWB receiver on FPGA (Field Programmable Gate Array).
