Talk Outline ● Project Overview ● Background ● Current Implementations ● Our Solution ● Constraints ● Gantt Chart ● Demo Day Plans

Project Overview ● Create a VDES system that can be used by the Coast Guard ● Software Defined Radio ● Benchtop Model Using USRP

Background ● Important to communicate information for ships ● 3 systems, 2 channels, with different frequencies ● Each transmits different information ● Currently only AIS is implemented

Solution ~ Software Defined Radio Hardware ● Coast Guard Radio ● AIS → ASM → VDE ● Transmitter → Receiver Software ● Open-source ● GNU Radio Companion ○ MATLAB Code

AIS Receiver - MATLAB

AIS Transmitter - GNU Radio

AIS Receiver - GNU Radio

Whats Next? ● Further testing and documentation of AIS code ● Document ASM code and layout algorithm ● Alter AIS Receiver Matlab code to receive ASM signals ● Alter AIS Transmitter Matlab code to transmit ASM signals

Constraints ● Online Schooling ○ Limited equipment ● Time ● Lack of VDE Knowledge

Project Management - Gantt Chart

Demo Day Plan ● Leading Up: Follow all emails sent to us. Contact Sponsors to ensure they know about Demo Day. ● On Demo Day ○ Show Simulation Results ○ Explain Algorithms Used
