OPTIMAL SMOOTHING FOR MICROPHONE ARRAY POST-FILTERING UNDER A COMBINED DETERMINISTIC-STOCHASTIC HYBRID MODEL
《Journal of Electronics(China)》2011年第4期524-530,共7页Hu Xiaohu Zheng Chengshi Li Xiaodong 
Supported by the National Natural Science Foundation of China (No. 61072123)
This paper shows the importance of the optimal smoothing scheme in Microphone Array Post-Filtering(MAPF) under a combined Deterministic-Stochastic Hybrid Model(DSHM).We reveal that some of the well-known MAPF algorith...

SMOOTHING OF 1/F SIGNAL WITH ORTHOGONAL MULTIWAVELET
《Journal of Electronics(China)》2006年第2期318-320,共3页Yan Xiaohong Zhang Taiyi Liu Feng 
Supported by the National Laboratory of Space Microwave Technology Foundation(No.51473030105JB3201).
Based on the orthogonal multiwavelet model of 1/f signals, smoothing fractal signals from white Gaussian noise with multiwavelet filter is proposed. The proposed multiwavelet method is very simple and easy to realize....

MODE SPACE SMOOTHING ALGORITHM TO ESTIMATE DOA OF COHERENT SIGNALS IMPINGING ON UNIFORM CIRCULAR ARRAY被引量：1
《Journal of Electronics(China)》1998年第4期289-295,共7页Ma Changlin Peng Yingning Tian Lisheng Liu Jianhua(Department of Electronic Engineering, Tsinghua University, Beijing 100084) 
A novel method to estimate DOA of coherent signals impinging on a uniform circular array( UCA) is presented in this paper. A virtual uniform linear array (VULA) is first derived by using spatial DFT technique, transfo...

ANALYSIS OF THE LEAKY BUCKET OUTPUT PROCESSES FOR BURSTY SOURCES IN ATM NETWORKS
《Journal of Electronics(China)》1997年第3期228-235,共8页Liao Jianxin(National Lab. of Switching Tech. and Telecom. Networks BUPT of China, Beijing 100088)Li Lemin Sun Hairong(National Key Lab. of Optical Fiber Commun. UEST of China, Chengdu 610054)
