Abstract :
An overview of the requirements of a scrambler for use with mobile radio equipment is presented. Details of the implementation of a scrambler are given satisfying these requirements. The scrambler is realized using general-purpose DSP technology giving the benefits of low-cost, high-volume production with the flexibility of customization and enhancement though software configuration
