WebSo-called Zadoff–Chu sequences [71] have the property of constant power in both the frequency and time domains. The elements of a Zadoff–Chu sequence of length MZC can be expressed as: (11.1) where u is the index of the Zadoff–Chu sequence within the set of Zadoff–Chu sequences of length MZC. From the point of view of small power ...

In telecommunications and recording, a scrambler (also referred to as a randomizer) is a device that manipulates a data stream before transmitting. The manipulations are reversed by a descrambler at the receiving side. Scrambling is widely used in satellite, radio relay communications and PSTN modems. See more In telecommunications, a scrambler is a device that transposes or inverts signals or otherwise encodes a message at the sender's side to make the message unintelligible at a receiver not equipped with an … See more A scrambler (or randomizer) can be either: 1. An algorithm that converts an input string into a seemingly random output string of the same length (e.g., by pseudo-randomly selecting bits to invert), thus avoiding long sequences of bits of the same value; in this … See more The first voice scramblers were invented at Bell Labs in the period just before World War II. These sets consisted of electronics that could mix two … See more Descramble in cable television context is the act of taking a scrambled or encrypted video signal that has been provided by a cable television company for premium television services, processed by a scrambler and then supplied over a coaxial cable and … See more Additive (synchronous) scramblers Additive scramblers (they are also referred to as synchronous) transform the input data stream by applying a pseudo-random binary sequence (PRBS) … See more It was the need to synchronize the scramblers that suggested to James H. Ellis the idea for non-secret encryption, which ultimately led to the invention of both the See more • Ciphony • Cryptography • Cryptochannel • One-time pad See more WebThis is where the band is split and then each band is inverted separately.
