| Abstract: | The purpose of this paper is to show a direct sequence spread spectrum system (DSSSS) with a transmitted reference.The code synchronization circuit is a very important and difficult part of the DSSSS.In many applications,for example,a remote control system or a wireless local area network(WLAN),this way can be used to simplify the code synchronization circuit,so as to reduce the volume and the cast of the receiver.The paper gives an example circuit of DSSSS with transmitted reference and the simulation results. |
