8th IEEE Sensor array and Multichannel Signal Processing Workshop (SAM)
作者: Han, Keyong Nehorai, Arye Washington Univ Preston M Green Dept Elect & Syst Engn St Louis MO 63130 USA
We consider the problem of using linear nested arrays to estimate the direction of arrival (DOA) of spatially distributed sources and detect the source number, where we have more sources than the actual physical senso... 详细信息

Annual Summit and Conference of the Asia-Pacific-Signal-and-Information-Processing-Association (APSIPA ASC)
作者: Xie, Julan Cheng, Fanghao He, Zishu Li, Huiyong Univ Elect Sci & Technol China Sch Informat & Commun Engn Chengdu Peoples R China
A novel DOA method is proposed to deal with the DOA estimation in the presence of the unknown mutual coupling for nested arrays. By using a new expression of the steering matrix in the presence of mutual coupling, a n... 详细信息

作者: Nannuru, Santosh Gerstoft, Peter Koochakzadeh, Ali Pal, Piya Univ Calif San Diego Scripps Inst Oceanog La Jolla CA 92093 USA Univ Calif San Diego Elect & Comp Engn La Jolla CA 92093 USA
Sparse Bayesian learning (SBL) has been used to obtain source direction-of-arrivals (DoAs) from uniform linear array (ULA) data. The maximum number of sources that can be resolved using a ULA is limited by the number ... 详细信息

47th IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
作者: Chen, Yuan-Pon Liu, Chun-Lin Natl Taiwan Univ Dept Elect Engn Taipei 10617 Taiwan Natl Taiwan Univ Grad Inst Commun Engn Taipei 10617 Taiwan
Sparse arrays with fourth-order cumulant processing can identify up to O(N-4) source directions with only N physical sensors. To achieve this property, the fourth-order difference co-array is preferable to own a conti... 详细信息
