IEEE Global Communications Conference (GLOBECOM)
作者: Shi, Cong Wang, Ying Zhang, Ping Minist Educ Key Lab Universal Wireless Commun Beijing Peoples R China
In this paper, we study joint spectrum sensing and resource allocation for heterogeneous services in multi-band cognitive radio systems. Two types of services are considered: delay-sensitive (DS) services and delay-to... 详细信息

IEEE Radar Conference (RADAR)
作者: Hammond, G. Barry Jackson, Julie Ann Air Force Inst Technol Dept Elect & Comp Engn Wright Patterson AFB OH 45433 USA
We apply a molecule dictionary approach to synthetic aperture radar canonical feature extraction. These canonical features capture physically-relevant scattering geometry as a function of shape type, frequency, aspect... 详细信息

12th IEEE International Workshop on Signal Processing Advances in Wireless Communications
作者: Aggarwal, Rohit Assaad, Mohamad Koksal, C. Emre Schniter, Philip Ohio State Univ Dept ECE Columbus OH 43210 USA Supelac Dept Telecom Gif Sur Yvette France
In this paper, we address the problem of joint scheduling and resource allocation in the downlink of an orthogonal frequency division multiple access (OFDMA)-based wireless network when the per-user SNR is known only ... 详细信息

Annual Conference on Information Sciences and Systems
作者: Wang, Ning Yang, Liuqing Department of Electrical and Computer Engineering University of Florida Gainesville FL 32611 United States Department of Electrical and Computer Engineering Colorado State University Fort Collins CO 80523 United States
As a powerful tool to convert nonconvex problems into convex ones, semidefinite programing (SDP) has been introduced to both cooperative and non-cooperative localization systems. In this paper, we derive the Cramé... 详细信息
