Design a MIL-STD-188-220c Compatible Radio Digital Message Transfer Device Adapter

摘要

The MIL-STD-188-220 protocol is the interconnection standard between DMTDs in battlefield of America DOD. It''s the only standardized protocol in tactical mobile networks by now. The protocol models and performance simulations are widely discussed, but mostly based on software simulations and rarely in the implementation issues. This paper is mainly focused on the protocol implementations and system performance analysis. The implementation is a MIL-STD-220C compatible device, which completing the entire data link layer operation and a part of network layer operation in a single FPGA(field programmable gate array) chip to achieve minimum response time and stable performance. The communication adapter function diagram, working flowchart and performance figures are listed.
