Chapter 4 Concept of Jamming

4.1 Introduction to Jamming

There are various different jamming models that can be seen in Figure 13 below. Figure

13a depicts the most benign jammer known as a barrage noise jammer. This type of jammer

transmits band limited white Gaussian noise across the power spectrum that covers the same

frequency range as the spreading signal. Figure 13c shows a single-tone jammer, which

transmits an unmodulated carrier in the spread signal bandwidth. This jammer is quite effective

and easy to implement in DSSS systems, however requires the tone to be placed at the center of

the spread signal bandwidth to achieve maximum effectiveness.
