Design and testability aspects of mobile adhoc networking waveform physical layer for software defined radio

Abstract

Software Defined Radio (SDR) is an emergent technology for future network centric operations as it can support dynamism of Mobile Adhoc Networking (MANET) waveforms through its inherent benefits of re configurability, portability and reusability. Unlike conventional radio, designing Physical layer for MANET waveform over SDR platform demands a new design approach and consequently must be tested thoroughly for basic radio transceiver functions as well as MANET configurations. In this paper, testability aspects of MANET waveform are discussed along with its design, development and testing in context of SDR. The test methodology has been developed considering various aspects of waveform design and system integration components. The testing results of baseband and RF subsystem of physical layer have also been presented in this paper.
