Fundamentals of spread-spectrum techniques

WebSpread Spectrum is being used because of a number of attractive properties. Spread spectrum techniques had originally appealed to military systems applications. These attractive properties are partially attributed to the PG. They are used to improve: • Anti-jamming performance. • Low probability of intercept, and • Multiple Access communications. Webspread spectrum is a CDMA access. The key must be defined and known in advance at the transmitter and receiver ends. Growing examples are IS-95 (DS), IS-98, Bluetooth, … michelle thrasher
