Xiaogang Xie, Tongbin Yu, Zuping Qian, Lei Zhang, Ying Liu
Compared with bistatic RCS, the monostatic RCS calculation is more difficult for the needs of surface current on scatterer induced by the incident wave of every single angle, so the calculation burthen is very large. Based on the character of “impedance matrix of MOM is invariable whether the angle of...

A Reliable Cooperative Spectrum Sensing Strategy for Cognitive Radios

Shoutao Lv, Zeyang Dai, Jian Liu
In cognitive radio networks (CRNs) , the secondary users (SUs) need to continuously detect whether the primary users (PUs) occupy the spectrum. In order to improve the spectrum sensing accuracy, a novel reliable cooperative spectrum sensing strategy based on the detection results relayed twice from the...

Analysis of Microstrip Circuit by Using Finite Difference Time Domain (FDTD) Method

Lei Zhang, Tong-bin Yu, De-xin Qu, Xiao-gang XIE
The microstrip circuit is mostly analyzed in transform domain, because its equivalent circuit equation is often nonlinear differential equation, which is easily analyzed in transform domain relatively, but hardly did in time domain, so the analysis of microstrip circuit is a hard work in time domain....

A Novel Frequency Locked Loop Based on Stochastic Resonance

Weitong Zhang, Zhiqiang Li, Wenming Zhu
Frequency locked loop (FLL) plays an important role in carrier synchronization because of its excellent dynamic performance. However, it performs inadequately in low signal-to-noise ratio (SNR). In this paper, the principle of stochastic resonance (SR) is briefly introduced and a SR processor is proposed....

A Double Semantic Network for Intelligent Search

Guogang Li, Tao Feng, Guoqiang Li, Hua Wang
The traditional semantic network retrieval has the following two urgent problems to be solved . The first problem is that the two concepts on the surface look very relevant, but vocabulary used to describe the two concepts has no contact, and in fact ,the two concepts are very poorly correlated. The...

Design of Unsymmetrical Doherty Power Amplifier for 460MHz LTE-Advanced Applications

Chuanhui Ma, Wensheng Pan, Youxi Tang, Chaojin Qing
An unsymmetrical Doherty power amplifier (DPA) at 460MHz is presented in this paper. The carrier and peaking amplifier of the DPA, which base on two equal-sized devices, are matched with different networks to mitigate the performance degradation caused by the limited load modulation. Measured with continuous...
