| Abstract: |
| This paper presents a design scheme of direct sequence spread spectrum(DSSS)system of digital intermediate frequency(IF) based on software radio according to the principle of direct sequence spread spectrum. And it is implemented by programmed digital devices. The experiment result indicates that the means of implementation can meet the requirement of design. The system also has the flexible and general characteristics. |
| Key words: Direct sequence spread spectrum(DSSS),Software radio,Programmed digital device |
