Comparative analysis of Gold Codes with PN codes using correlation property in CDMA technology

In a spread spectrum modulation system all users of the channel transmit information at the same time over the whole channel. Because information transmitted this way simply resembles noise, it is hard to intercept and therefore it offers high security. This techniques have a number of advantages over other multiplexing systems includes better frequency efficiency, power utilization and noise flexibility. This paper is prepared on the basis of aims on study of correlation properties among Gold code sequence and ordinary pseudo noise codes sequence. This paper however is also simulation of production of speared signal and re produce the original message signals. Two Gold Codes sequences and two Pseudo Noise sequences are to determine which is a better means for modulating the given message signal in terms of better noise immunity and security with the help of MATLAB.
