The same data signal is also phase modulated onto the carrier using a 512-bit long pseudorandom sequence (direct-sequence spreadspectrum modulation). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The radios use direct-sequence spreadspectrum coding, which is managed by the digital stream into the modulator. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Spreadspectrum avoids cochannel interference between adjacent cells, since the probability that users in nearby cells use the same spreading code is insignificant.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A spreadspectrum technique spreads the bandwidth of the data uniformly for the same transmitted power. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Spreadspectrum involves starting a modulation at one frequency, and altering the frequency during its cycle. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. They have been extensively studied for their applications in cryptography, but have also been applied to spreadspectrum, coding theory, and combinatorial design.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Some properties of chaotic dynamics, such as complex behaviour, noise-like dynamics (pseudorandom noise) and spreadspectrum, are used to encode data. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Frequency hopping is a basic modulation technique used in spreadspectrum signal transmission. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Spreadspectrum signals are sent down the wire and then the reflected signal is observed. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This patent did pre-empt spreadspectrum radio technology, but the frequency-hopping it describes is primarily applied to the radio carrier frequency, not the signal coding. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. As with other spreadspectrum technologies, the transmitted signal takes up more bandwidth than the information signal that modulates the carrier or broadcast frequency. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The figure shows how a spreadspectrum signal is generated.
