TELON is an application development system currently sold and maintained by CA Technologies (formerly CA, Inc. and Computer Associates International, Inc.). When it was introduced in 1981, it was one of the first computer-aided software engineering ("CASE") tools on the commercial market. The developer tools run on IBM 's MVS operating systems ...
A set of Gold code sequences consists of 2 n + 1 sequences each one with a period of 2 n − 1. A set of Gold codes can be generated with the following steps. Pick two maximum length sequences of the same length 2 n − 1 such that their absolute cross-correlation is less than or equal to 2 ( n +2)/2 , where n is the size of the linear-feedback ...
A pseudo-noise code (PN code) or pseudo-random-noise code (PRN code) is one that has a spectrum similar to a random sequence of bits but is deterministically generated. The most commonly used sequences in direct-sequence spread spectrum systems are maximal length sequences , Gold codes , Kasami codes , and Barker codes .
Rolling code. A rolling code (or sometimes called a hopping code) is used in keyless entry systems to prevent a simple form of replay attack, where an eavesdropper records the transmission and replays it at a later time to cause the receiver to 'unlock'. Such systems are typical in garage door openers and keyless car entry systems.
In the debut episode of “Distractible,” the guys discuss all things hair-related — including talking about the dangers of hair removal and imagining a sci-fi world in which an elite class ...
The Hadamard code is a linear code, and all linear codes can be generated by a generator matrix .This is a matrix such that () = holds for all {,}, where the message is viewed as a row vector and the vector-matrix product is understood in the vector space over the finite field.
In computing, code generation is part of the process chain of a compiler and converts intermediate representation of source code into a form (e.g., machine code) that can be readily executed by the target system. Sophisticated compilers typically perform multiple passes over various intermediate forms. This multi-stage process is used because ...
