Correlation analysis of the gold codes and walsh codes in CDMA technology

Several customary forms for cellular phone communication have been developed through out the planet. Each mobile standard has been developed to meet the particular requirements of the country or interest involved in its specification. The wireless communication system has grown extremely fast, with the demand doubling roughly every two years. The increasing number of wireless users has spurred communications engineers to improve the quality of service. Cellular mobile radio systems aim to provide high spread spectrum signals for digital communications to provide resistance to hostile jamming; to hide the signal by transmitting it at low power, thus, making it difficult for an unintended listener to detect its presence in noise; to make it possible for multiple user to communicate through the same channel. Basically, CDMA system is noise limited, not bandwidth limited. Because the capacity of the CDMA system is depend on signal to noise ratio. It is possible to minimize the noise by using the Gold codes than the usual code.
