Gold code

A set of Gold codes can be generated with the following steps.

As well, the Gold codes have good auto-correlation properties.

This is done by assigning each satellite a unique binary sequence known as a Gold code.

The group obtained a duplicate nuclear football and Gold Codes card, and kept it in the situation room.

Gold codes have bounded small cross-correlations within a set, which is useful when multiple devices are broadcasting in the same frequency range.

Gold codes are named after Robert Gold.

The Correlation Tag is a Gold code, and contains inherent error tolerance.

The exclusive or of two Gold codes from the same set is another Gold code in some phase.

To confirm the President's identity, he must give a special code (called the "Gold Codes") on a card known as "the biscuit".

Gold codes are an example of a PN suitable for this purpose, as there is low correlation between the codes.

But rather than review the preview edition, we waited until the gold code came out so that we could give the product a full round of tests.

These Gold codes are highly mutually orthogonal, so that it is unlikely that one satellite signal will be misinterpreted as another.

These Gold codes are quite often referred to as pseudo random noise since they contain no data and are said to look like random sequences.

The set of the 2 1 exclusive-ors of the two sequences in their various phases (i.e. translated into all relative positions) is a set of Gold codes.

The receiver uses the C/A Gold code with the same PRN number as the satellite to compute an offset, O, that generates the best correlation.

The most commonly used sequences in direct-sequence spread spectrum systems are maximal length sequences, Gold codes, Kasami codes, and Barker codes.

Ernest Doku editor of Omio.com explained: "We knew of the Gold code name denoting HTC Windows Phone 7.

A Gold code, also known as Gold sequence, is a type of binary sequence, used in telecommunication (CDMA) and satellite navigation (GPS).

The Gold Codes are the nuclear launch codes that are purportedly provided to the President of the United States of America in his role as Commander in Chief.

As early as 1982 it was discovered that maximum length sequences based on bent functions have cross-correlation and autocorrelation properties rivalling those of the Gold codes and Kasami codes for use in CDMA.

The results of these modulo 2 additions are the 50 bit/s navigation messages from satellites n through n. The Gold codes used in GPS are a sequence of 1,023 bits with a period of one millisecond.

CPGPS uses the L1 carrier wave, which has a period of , which is about one-thousandth of the C/A Gold code bit period of , to act as an additional clock signal and resolve the uncertainty.
