Some of the leading applications of spread spectrum techniques in America are briefly described. Outstanding problems with some of these applications are highlighted. This leads to a description of a very few of the variety of techniques being applied to solve these problems. We first consider commu...

In addition to these conventional applications of transform-domain signal processing, there has been a rapidly growing activity in new application areas—namely, spread spectrum communication, discrete multitone (DMT) modulation, low probability of intercept (LPI) communication, radar signal processing, ...
When the many techniques for mitigating the generation of EMI fail to provide the necessary noise margin, the application of spread- spectrum frequency dithering (SSFD) may provide a solution. This topic explores modulation techniques, models the behavior in SPICE, and examines real-world behavior ...
