Abstract
The present invention is a method and apparatus for providing a pseudo random sequence for a spread spectrum system that prevents interception and provides real estate and power consumption efficiency. A pseudo random sequence may be created in real-time by associating a pseudo random sequence of a channel location of the carrier frequency at an instant in time. For example, the entire band of the spread spectrum system may be scanned to detect a channel with a low received signal strength. The location of the channel, or the actual frequency of the channel, could be associated with a particular pseudo random sequence to create a hop set for frequency hopping. Additionally, the location of a characteristic of the spread spectrum system, such as a noise characteristic, could be utilized to determine a content of a pseudo random sequence.
