The enormous popularity of Web 2.0 social network services has led to much research on social network analysis (SNA). These studies focus on analyzing the complex interactive activities between users in the world of virtual networks. SNA has shown great potential in automatic document classification, especially in identifying citation networks of research papers and the references among them. This...
This paper researched on KEELOQ algorithm and presented a wireless anti-theft system based on the KEELOQ technology. The system has one central controller and no more than eight monitors. When the whole wireless anti-theft system were designed, a physical testing about one hundred days was made. The results showed that the system works stably.
A novel blind multiple carrier frequency offset (multi-CFO) estimation algorithm is developed for distributed multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) systems over frequency-selective fading channels. In the algorithm, different multiple CFOs are estimated by cyclostationarity (CS) of the received signals and least square (LS) criterion. Theory analysis shows...
The difficulty in solving the discrete logarithm problem (DLP) is very important to the cryptography since it is widely used in signature schemes, message encryption, authentication, and so on. The baby-step giant-step algorithm is a series of well-defined steps to compute the discrete logarithm, but its gigantic storage cost is an obvious disadvantage. The paper designs a new algorithm to compute...
