| Abstract: | This paper demonstrates major performances and direction for use of all digital direct sequence spread spectrum STEL-2000A chip.With STEL-2000A chip as the core,assisted with several peripheral parts such as A/D,D/A and smart controller,a spread spectrum communication system is designed for field environment.The system consists of three parts:selection of systematic parameters,designs of hardware and software.The hardware design gives emphasis on interface design of STEL-2000A,while the software focuses on the internal programming of STEL-2000A.Finally,the debugging results are presented. |
