| Abstract: | In this paper,the direct sequence spread spectrum communication synchronous is studied,and the PN codes are used as spread sequences for their good correlation.The synchronization of transmitting and receiving systems are implemented by a new sliding correlating mode.The FPGA design of synchronized technology is also discussed.The software simulation is made with the software of ISE 10.1 and the results show that the time of computation and synchronous capturing time are reduced in application of this metho... |
