Two kinds of controllable doped left-handed materials (DLHMs) were designed by inserting inductors and capacitors into the traditional left-handed material (LHM) as heterogeneous elements respectively, which are D...
On the basis of various firewall-penetrated technologies, a novel firewall-penetrated technology based on trusted host, which can realize the communication between penetrating host and protected host, is proposed in t...
The design and analysis of special type beam former, the Butler matrix, toachieve orthogonal beam-forming networks is presented in this paper. A 4 X 4 microstrip planar arrayantenna is assumed to simulate a 4 X 4 Butl...
The multi-carrier code division multiple access (MC-CDMA) system is extended to the coded MC-CDMA system. This system combine the channel error correcting coding (ECC) with MC-CDMA systems, thus sufficiently exploitin...
