What is it? Why is it important? What issues are addressed? How does it work?
Spread spectrum is a technique used for transmitting radio or telecommunications signals. Spread spectrum is an important component of code division multiple access (CDMA) technology, which is used in cellular telecommunications. The issues that spread spectrum addresses are noise reduction, security and resistance to jamming and interception (Janssen). …show more content…
The process of re-collecting a spread signal spreads out the interfering signal, causing it to recede into the background.
Spread-spectrum signals are difficult to intercept. A spread-spectrum signal may simply appear as an increase in the background noise to a narrowband receiver. An eavesdropper may have difficulty intercepting a transmission in real time if the pseudorandom sequence is not known.
Spread-spectrum transmissions can share a frequency band with many types of conventional transmissions with minimal interference. The spread-spectrum signals add minimal noise to the narrow-frequency communications, and vice versa. As a result, bandwidth can be used more efficiently.
