A Gold code, also known as Gold sequence, is a type of binary sequence, used in telecommunications [1] and satellite navigation . [2] Gold codes are named after Robert Gold. [ 3 ] [ 4 ] Gold codes have bounded small cross-correlations within a set, which is useful when multiple devices are broadcasting in the same frequency range.
The Gold Code is the launch code for nuclear weapons provided to the President of the United States in their role as commander-in-chief of the armed forces. [1] In conjunction with the nuclear football , the Gold Codes allow the president to authorize a nuclear attack. [ 2 ]
Hospital emergency codes are coded messages often announced over a public address system of a hospital to alert staff to various classes of on-site emergencies. The use of codes is intended to convey essential information quickly and with minimal misunderstanding to staff while preventing stress and panic among visitors to the hospital.
The C/A PRN codes are Gold codes with a period of 1023 chips transmitted at 1.023 Mchip/s, causing the code to repeat every 1 millisecond. They are exclusive-ored with a 50 bit/s navigation message and the result phase modulates the carrier as previously described .
Desktop Gold doesn't provide dial-up internet connectivity and can only be used if you already have a broadband internet connection. If you're having trouble getting online, check to see if the issue is with your internet connection.Our help article, Troubleshooting a Broadband Connection , provides some useful troubleshooting tips.
Gold codes are an example of a spreading sequence suitable for this purpose, as there is low correlation between the codes. If all of the users are received with the same power level, then the variance (e.g., the noise power) of the MAI increases in direct proportion to the number of users.

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.
