Which code is known as Gold code?

A gold code is a set of random sequences, often called pseudo-noise (PN) sequences, that are statistically uncorrelated. Gold codes are used in CDMA as chipping sequences that allow several callers to use the same frequency, resulting in less interference and better utilization of the available bandwidth.

How do you make a gold code?

A set of Gold codes can be generated with the following steps. Pick two maximum length sequences of the same length 2n − 1 such that their absolute cross-correlation is less than or equal to 2, where n is the size of the linear-feedback shift register used to generate the maximum length sequence (Gold '67).

How many gold codes are there?

For this situation there are 65 different Gold-codes available and the maximum full-code cross-correlation is 17.
