Abstract :
This article discusses about spread-spectrum technique, the goal is to deliberately spread the transmitted electromagnetic energy in the frequency domain and receive the user data signal using the same pseudo random code used in the transmitter. Critical advantages of DSSS systems are related to their ability to provide secure communication and be robust against continuous time narrow band jamming with low spectral density power.
