Advanced Signal and Information Processing for Managing Interference in Radio Communication Systems
Abstract
In support of the Office of Naval Research s interests in interference mitigation and with its recent successes in waveform interfer,ence and machine learning techniques, Louisiana State University (LSU) proposes the establishment of a research, development, and te,aching lab to offer ONR enhanced capabilities in assessing capacity and limitation of interference excision systems (IES) to protect, signals of interests (SOI) in the presence of potentially aggressive and/or inadvertently produced interference sources in radio co,mmunication systems. Beyond helping improve confidence in all pre-service IES devices, LSU s testbed environment will enable the stu,dy of a novel and paradigm-shifting design methodology for interference countermeasure via learning driven ensemble-IES (LEn-IES) an,d time-frequency recovery of corrupted signals (LTF-RCS) in support of a singular goal: communication supremacy for the warfighter.T,he instruments to acquire using the DURIP funds shall enable us to build a wired and integrated testing system/platform over which w,e can generate multiple types of complex interference signals and SOIs for evaluation and assessment. The environment will include c,ommercially available satellite communication (SATCOM) modems, a vector signal generator and analyzer, as well as generic software d,efined radios (SDR), to serve the purposes of SOI transmitter and receiver, interference generators, and radio channel emulators. IE,S devices from vendors such as MagiQ, iDirect, Adaptive Dynamics, and Metamagnetics, as well as waveforms to include Protected Tacti,cal Waveform (PTW), Direct Sequence Spread Spectrum (DSSS) waveforms, Soldier Radio Waveform (SRW) will be made available to us thro,ugh U.S. Navy NAVWAR PEO C4I, PMW/A-170. By equipping our testbed with multiple probing ports, we can collect and mine RF data in bo,th time and frequency domains throughout communication processing channels for learning driven assessment metrics and IES solutions., Through this adaptive environment, we will provide translational research and well justified testing methods to both developers and, testers of IES devices.Talent development is central to our support mission. Students at both the senior undergraduate (UG) and gra,duate levels will take newly developed lab-based courses on interference testing and measurements. They will work on projects where,they form teams playing on offense (red interferer) and defense (blue SOI and/or IES) to design waveforms and signal processing algo,rithms. We will organize intramural competitions among teams to compete against each other on the testbed and award winners who can,deliver either "the strongest shield" or "the sharpest spear" under prescribed boundary constraints. Our goal is to build the lab in,to a powerful and recognized enabler for signal-game-oriented pedagogical approaches to teaching students in the areas of communicat,ion and advanced signal processing.It is expected that research tasks and related education modules developed and tested in this lab, will serve to train and energize an emerging workforce in the RF and SATCOM fields. The body of advanced knowledge and young talent,s produced from this program can be leveraged by the DoD to further enhance its competitive advantage in RF communications for the w,arfighter.
