Abstract
To investigate the multiplexed communication in a chaos system with semiconductors subject to optical feedback and optical injection where delays are modulated by signals, the encryption is realized through modulating the channel delay with the corresponding user' s signal and the decryption is implemented utilizing chaos synchronization and cross correlation measurement by numerical simulation. The multiplexing and de-multiplexing of three user' s signals of 1 Gbit/s were realized. Also, the conditions for efficient decryption and the main factors affecting bit error were analyzed.关键词
