| Abstract: |
| According to the public Link16 information criteria, a JTIDS transmi
ssion code generator is designed combining with the requirements for ta
ctical data link(TDL), in which submodules such as RS encoding, interleaving, CC
SK, a
nd CCSK codes encryprion are contained. Based on the principle of Link16 transmi
ssion code generator, the submodules are designed and the scheme of hardware imp
lementation is given. Systemic synthesis and simulation for the transmission cod
e generator are accomplished on the Quartus II software platform with Cyclone II
FPGA chip EP2C8Q208C8, and is verified on the development board with C
yclone II FPGA chip. The hardware product can be used to test and evaluate the
function of the data link and so on. |
