摘要
对直接扩频通信同步系统进行了研究,使用PN码作为扩频序列,利用其良好的自相关性,提出一种新式的滑动相关法使收发端同步,并给出该系统的FPGA实现方法。利用ISE 10.1开发软件仿真验证,证明此方法可以提高运算速度,减少捕获时间。
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 slid- ing 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 method.
