| Abstract: |
| The anti-jamming code used in a data communication system is analyzed, then software and hardware realization methods based on the Very Large Scale Integration (VLSI) technology are put forward. Furthermore, several improvements that can greatly improve its communication security and anti-jamming performance are proposed, and these ideas also have universal design guidance in all kinds of datalink. Finally its FPGA-based realization and simulation results of the decoder are introduced, which can be adapted to higher data rate requirements in wide-band wireless networks. |
