In our study of this system directly spread spectrum systems, this system uses many code to spread data bits of communication.There are different types of code sequences available with good correlation properties,And they often use Pesudo sequence to spread as it is less efficient in protecting information from the breaches that attack the communications systems from penetration. But we will use Gold sequence it as it is better and more complex than the rest of the code sequence ( Pn Sequence , Barker Code, Hadamard Code , And others) in terms of the security aspect of the information, as well as it is difficult to detect the information sent in addition to that it is used in Code-division multiple access (CDMA). In our articles we design and implement difficult code in the protection of information in the communication system. Where we implemented this system using MATLAB to send as well as to send a binary data and  color photo (RGB).To make sure our system is working properly and with few errors, as well as better information protection than the rest of the other code that is used in direct sequence spread spectrum.
