Spread spectrum - Wikipedia
WEBIn telecommunications, especially radio communication, spread spectrum are techniques by which a signal (e.g., an electrical, electromagnetic, or acoustic) generated with a particular bandwidth is deliberately spread in the frequency domain over a …
What is Spread Spectrum? - GeeksforGeeks
WEBJul 16, 2024 · Spread Spectrum is a wireless communication technology that distributes the transmitted signal across a larger bandwidth than the original signal. This approach improves communication security and dependability by increasing the signal’s resistance to interference, eavesdropping, and jamming.
Spread Spectrum Communications - Definition & Techniques - NI
WEBAug 13, 2024 · Spread spectrum systems spread a signal over a wider frequency band than the original message while transmitting at the same signal power, making it harder to intercept or jam. This tutorial covers an introduction to RF, wireless and high-frequency signals and systems.
An Introduction to Spread-Spectrum Communications - Analog
WEBA complete spread-spectrum communication link requires various advanced and up-to-date technologies and disciplines: an RF antenna, a powerful and efficient PA, a low-noise and highly linear LNA, compact transceivers, high-resolution ADCs and DACs, rapid low-power digital signal processing (DSP), etc.
Spread Spectrum - an overview | ScienceDirect Topics
WEBSpread Spectrum refers to a system in which the transmitted signal is spread over a wide frequency band, much wider than the bandwidth required to transmit the message. This system uses a spreading code to modulate the message signal, resulting in a modulated baseband signal with a much higher rate and wider spectrum than the original message.
WEBSpread spectrum systems is a class of (primarily) wireless digital communication systems specifically designed to overcome a jamming situation, i.e., when an ad- versary intends to disrupt the communication.
Introduction to Spread Spectrum Communication Systems
WEBSpread spectrum (SS) technology is used in multiple access communication to increase resistance to signal interference from multiple transmission paths and to increase bandwidth efficiency. In this chapter, we describe several digital modulation techniques that are used in spread spectrum communication.
