  2. Pseudorandom noise - Wikipedia

    en.wikipedia.org/wiki/Pseudorandom_noise

    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 .

  3. Non-uniform random variate generation - Wikipedia

    en.wikipedia.org/wiki/Non-uniform_random_variate...

    Non-uniform random variate generation or pseudo-random number sampling is the numerical practice of generating pseudo-random numbers (PRN) that follow a given probability distribution. Methods are typically based on the availability of a uniformly distributed PRN generator .

  4. Pseudorandom number generator - Wikipedia

    en.wikipedia.org/wiki/Pseudorandom_number_generator

    A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), [1] is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers.

    There are two navigation message types: LNAV-L is used by satellites with PRN numbers 1 to 32 (called lower PRN numbers) and LNAV-U is used by satellites with PRN numbers 33 to 63 (called upper PRN numbers). [9] The two types use very similar formats. Subframes 1 to 3 are the same, [10] while subframes 4 and 5 are almost the same. Each message ...

  6. Modified Uniformly Redundant Array - Wikipedia

    en.wikipedia.org/wiki/Modified_Uniformly...

    One may note that if = + and =, a uniformly redundant array(URA) is a generated. As with any mask in coded aperture imaging, an inverse sequence must also be constructed. In the MURA case, this inverse G can be constructed easily given the original coding pattern A :

  7. Universities Research Association - Wikipedia

    The meeting eventually resulted in the decision to form the Universities Research Association, with 34 original members, to build and manage the new accelerator facility. URA filed its articles of incorporation on June 21, 1965. J. C. Warner, president of the Carnegie Institute of Technology, served as URA's first president.

  8. URA3 - Wikipedia

    en.wikipedia.org/wiki/URA3

    URA3 is a gene on chromosome V in Saccharomyces cerevisiae (yeast). Its systematic name is YEL021W.URA3 is often used in yeast research as a "marker gene", that is, a gene to label chromosomes or plasmids.
