Since collisions are so detrimental to network performance, methods have been developed to allow multiple transmissions on a broadcast network without necessarily causing mutual packet …

A specific example of the use of spread spectrum technology is the North American Code Division Multiple Access (CDMA) Digital Cellular (IS-95) standard. The CDMA employed in this standard uses …

Spread-spectrum techniques are used for the establishment of secure communications, increasing resistance to natural interference, noise, and jamming, to prevent detection, to limit power flux …

Jul 23, 2025 · Spread Spectrum is a wireless communication technology that distributes the transmitted signal across a larger bandwidth than the original signal. This approach improves communication …

Spread Spectrum multiple access (SSMA): In spread spectrum, the transmission bandwidth of the signals is several orders of magnitude greater than the minimum bandwidth required for transmitting …

Spread spectrum techniques can mitigate or coherently combine ISI, mitigate narrow-band interference and jamming, hide a signal below the noise floor or make it hard to track, or enable multiple users to …

Spread Spectrum Multiple Access Spread spectrum multiple access (SSMA) uses signals which have a transmission bandwidth whose magnitude is greater than the minimum required RF bandwidth.

In this problem we explore the inherent multiple access capability of spread spectrum signalling, i.e., the ability to support simultaneous transmissions in the same frequency band.

What is Multiple Access? Multiple users want to communicate in a common geographic area Cellular Example: Many people want to talk on their cell phones. Each phone must communicate with a base …

Since the spread-spectrum signal occupies a large bandwidth, only a small portion of this will undergo fading due to multipath at any given time. Like the narrow-band interference, this will result in only a …
