China co.munications 2009年第2期6卷 144-149页

作者： Rakesh Tamrakar Datang Mobile Teleco.munications equipment co. ltd

Beam-forming technique with small-spaced-array is based on the antenna （e.g. 0.5A）, known as smart antenna. The smart antenna array can generate directional beam towards the designated user more effectively than the antenna with largespaced-array （e.g. lOA） and thus obtain significant array gain. In network deployment and the testing, we observed that smart antenna enlarged the co.- erage, increased system capacity thus lowering the initial investment for operators, and at the same time flexible network co.figuration,

ZTE co.munications 2007年第3期5卷 1-5页

作者： Hu Jinling (Datang Mobile co.munications equipment co., ltd, Beijing 100083, China)

The High Speed Uplink Packet Access (HSUPA) technology for Time Division-Synchronous co.e Division Multiple Access (TD-SCDMA) is used to improve the overall uplink performance: to increase the peak data rate and throughput and to reduce the transmission delay of uplink. The co.sidered enhancements include Adaptive Modulation and co.ing (AMC), Hybrid Automatic Repeat Request (HARQ), Node B fast scheduling and sharing of uplink channel resources between User equipments (UE). New Media Access co.trol protoco. entities (MAC-e and MAC-es) are adopted to enhance and optimize protoco.s. Simulation results of these technologies show that the system performance (including the peak rate, throughput, and delay) can be improved significantly.

作者： Wei Qinghai China Electric Power equipment and Technology co., ltd. Zhong Zhaorui China Electric Power equipment and Technology co. Ltd.

Through analyses of the three transformations of IBM and the three management innovations of the State Grid co.poration of China (SGCC) and its co.sequential achievements, this paper co.dudes that the key to management is innovation. An enterprise can obtain co.e co.petitive advantages for sustainable development only if the innovation it makes is closely integrated with its management. Hereby SGCC has set up a good example for other state-owned enterprises to carry out innovational management.

求解约束L_∞问题的新算法

数值计算与计算机应用 1997年第1期18卷 20-29页

作者：贾国平上海贝尔电话设备制造有限公司技术开发部

This paper co.siders a kind of co.strained L_∞ probleme, which involving linear functions only, and presents a new algorithm for the solution of this problem. In co.siderationof the special structure of L_∞ problems, we reduce our problem into some small-scaleproblems by means of the Benders deco.position method and avoid solving large-scaleproblem directly. Our approach is also applicable to the unco.strained case. We finallygive some numerical examples and co.pare our approach with other algorithms for L_∞problems. These results show that our method for soiving L_∞ problem is efficient.
