10. A Prototype Biometric Security Authentication System Based upon Fingerprint Recognition.

Author

Xiang, Wei, Desai, Bhavin, Wen, Paul, Wang, Yafeng, and Peng, Tianshu

Abstract

In this paper, we have proposed a prototype biometrics authentication system based upon fingerprint recognition. The major functional blocks of the proposed authentication system are presented in details. A simple but effective algorithm is proposed to detect and remove false minutia, which is able to considerably improve the system performance. The performance of the developed system is demonstrated to have a high level of accuracy through experimentation. [ABSTRACT FROM AUTHOR]

11. Self-adapting Cyclic Delay Diversity System.

Author

Zheng, Aoyang, Wang, Yafeng, Yang, Dacheng, and Xiang, Wei

Abstract

Cyclic Delay Diversity (CDD) is a simple and efficient space-time diversity technique. It can be used in OFDM and DFT-Spread-OFDM. The traditional CDD has low complexity and system overhead, however, also has some limitations on performance and is sensitive to propagation environment. In this paper, two improved CDD scheme including open-loop and close-loop strategies for uplink and downlink of EUTRA LTE are introduced. Compared with the conventional method, the new schemes can obtain higher performance and less sensitivity to environment. [ABSTRACT FROM AUTHOR]
