Abstract :
The use of a microprocessor to control the synchronization of a low-data-rate spread-spectrum system is described. The microprocessor controls a voltage-controlled oscillator and sequence-generator, and carries out the correlation processes needed for the acquisition and tracking modes. Switching between modes is achieved by changing an interrupt vector.
