On the generation and correlation measurements of gold codes†

Abstract

Gold codes have many important applications, particularly in spread-spectrum code-division multiple-acess (CDMA) systems. The generation of Gold codes and the measurement of their correlation properties using some simple circuits are described in this paper. In particular, a circuit for the generation of m-sequences and Gold codes of 31 bits length and arbitrary phases, as well as a special digital matched filter circuit that is used to measure the correlation properties of these codes, are described in detail. Examples of the measured autocorrelation and cross-correlation functions of Gold codes are presented and compared with the corresponding computer generated results. © 1988, Taylor and Francis Group, LLC.
