—In this paper, a new PRN code optimal design based on unequal-length code modulation is proposed. The better performance of code acquisition in weak signals will be achieved by using this method, because the cross-correlations between different signals have been sliding, thus suppressing multiple access interference effectively. Theoretical analysis and(More)

Multicast routing protocols are widely used as efficient communication methods for Group-oriented applications. Decentralized system is preferred to improve bandwidth economization. However, security with the key management for such protocols remains a significant problem. In this paper, a secure group key agreement over decentralized systems is proposed.(More)
