IEEE TRANSACTIONS ON CONSUMER ELECTRONICS 2008年 第3期54卷 1048-1052页
作者: Zhu, Xiaodong Jiang, Tao Zhu, Guangxi Huazhong Univ Sci & Technol Elect & Informat Engn Dept Wuhan 430074 Peoples R China
In this paper, five novel schemes based on greedy algorithm are proposed to reduce the peak-to-average power ratio (PAPR) in orthogonal frequency division (OFDM) systems. For each proposed scheme, a simple transformat... 详细信息

OPERATIONS RESEARCH LETTERS 2000年 第4期26卷 193-197页
作者: Sviridenko, MI Univ Aarhus Basic Res Inst Comp Sci DK-8000 Aarhus C Denmark Sobolev Inst Math Novosibirsk Russia
In this work we consider the maximum p-facility location problem with k additional resource constraints. We prove that, the simple greedy algorithm has performance guarantee (1 - e(-(k+1)))/(k + 1). In the case k = 0 ... 详细信息

Improved performance of the greedy algorithm for partial cover
收藏 引用
INFORMATION PROCESSING LETTERS 1997年 第5期64卷 251-254页
作者: Slavik, P SUNY Buffalo Dept Math Buffalo NY 14214 USA
We prove that the classical bounds on the performance of the greedy algorithm for approximating MINIMUM COVER with costs are valid for PARTIAL COVER as well, thus lowering, by more than a factor of two, the previously... 详细信息
