A secure and robust self-encoded spread spectrum multiple-access approach for multimedia communication system

摘要

In multimedia communication, various data rates, security strategies, and data qualities are required for different content forms such as text, audio, images, video, and interactivity content forms. In this paper, we propose a secure and robust approach to achieve the multimedia multiple access (MA) communication using self-encoded spread spectrum (SESS). In this proposed system, SESS multiple access (SESS-MA) is a novel approach to multimedia system due to its unique secure and flexible spreading nature. Iterative detection is applied for an improved multimedia quality of service (QoS) at the receiver. The number of iterations needed is evaluated separately according to different multimedia contents. Simulation studies demonstrate that the proposed scheme ensures satisfactory data quality, security, and robustness.
