Abstract :
CDMA systems in comparison with other communication systems, are resistant against unauthorized information detection attacks, yet have some weakness with respect to some eavesdropping techniques. Increasing the physical layer built-in security through secure scrambling method is an advantageous method. Besides, using some capacity achieving codes such as LDPC codes, was shown that help the system for better secrecy and good performance. Here a LDPC coded CDMA system with AES scrambling as the secure method is described and analyzed. The performance of the system is acceptable along with all the security advantages mentioned above.
