Abstract :
This paper proposed one kind of synchronization design of double-PN QPSK-DSSS system which used for burst communication in high dynamic circumstance. The design uses a fully parallelized two-dimensional differential correlation peak search scheme to achieve the synchronization of a DSSS signal. The scheme of the algorithm that can implement in a FPGA is also given. The design can realize rapid synchronization in a DSSS system in condition of increasing suitable resource of FPGA.
