Fingerprint authentication is one of the most reliable and most widely used authentication methods. With the maturation of fingerprint recognition technology and the reducing cost of fingerprint reader, fingerprint authentication is more and more widely used in daily payment situation. This paper presents a new offline fingerprint payment system based on Artix-7 FPGA (XC7A35T-ICPG236C). This system...
Symbol timing synchronization is an important component in communication systems. The quality and reliability of wireless network communication will improve with accurate symbol timing recovery. In this paper, we present a symbol timing synchronization method by interpolating the samples at the output of the matched filter to compute the desired time instants. Since interpolation jitter is the major...
This paper analyzed the shortcomings that existed in the Memcached Caching Strategy. An improved scheme DCSAE (Data Cached Strategy on Asynchronously Updating for Eventual Consistency) which used asynchronous update based on the eventual consistency theory was proposed. DCSAE generated virtual nodes and assigned them to real nodes according to the weight of each node. The weight was calculated in...
With the rapid development of computer technology, Software-Defined Radio has become more and more popular. We can now transfer the communication system from hardware to software, which makes it more flexible and helps us virtualize the communication system. In this paper, we creatively introduce a method to guarantee hard real-time in user-space on Linux. Unlike the usual methods, Our method(real...
