This Grant is a continuation of N000141410104 A MAC-PHY Architecture & Smart Radio Prototype to Maximize Network Spectral Efficiency
Abstract
Year 1:Theoretical and Simulation work identifying a distributed optimization protocol.Specifics include:o Investigating alternative decision criteria for resource allocationo New approaches to iterative beamforming subject to interference and QoSconstraintso Near optimal policies governing band segmentationo Spectro-spatial power allocation to minimize interference footprintYear 2:Continue year 1 effort focused on identifying a distributed optimization protocolEach WARP radio has 2antenna portsThe JFW mesh module provides full bi-directionalconnectivity between all antenna ports. it also provides up to92 dB of independently controlled attenuation on any path50PMA-030 8 port mesh interconnect18 MAC-PHY co-design to maximize network spectral efficiencyo Identify and evaluate modified slotted ALOHA mechanism and conduct trade-offanalysis vis-a-vis a standard TDMA schemeo Model and exploit network dynamics and quantify its effect on the overall systemperformanceo Optimum band segmentation in a parallel acquisition strategyo Use of second order statistics to help bootstrap the beamforming and beamnullingalgorithms.Year 3: Continue year 2 efforts focused on the development and evaluation of the Slotted-ALOHA MAC with support for the iterative beamforming approach Study system performance under realistic operating environmentso Performance as a function of the offered loadImpact of topology variationo Evaluation under relevant military CONOPS (neighborhood clearing, Littoralspace, ?) Start the development of the Phase 1 Matlab-over-RF prorotypeYear 4: Complete Matlab-over-RF phase-1 prototype system and demonstrate it to the sponsorMigrate the phase-1 prototype system to phase 2 and enable real-time communication ina 1 MHz bandwidtho Port Matlab code to the radio?s onboard FPGA/DSPo Real time testing and debugging in a static indoor environmento Static and dynamic testing in outdoor environments representative of actualmissions Final demonstration to the customer of the unit?s ability to support multiple concurrentlinks with significant improvement in the network spectral efficiency (venue to be chosenby ONR).
