Although optimal transmit directions over generic correlated multiple-input multiple-output(MIMO) Rayleigh fading channels are well known to be the eigen beams defined by the transmit covariance matrix, the general issue of optimal transmit-beam number and power allocation remains unsolved. The current techniques heavily rely on the time-consuming Monte Carlo method. In this talk, by formulating the problem in the framework of Lagrange multipliers and by fully exploiting the algebraic structures and properties of the optimization problem at hand, we obtain a simple criterion for optimal beam number determination and a set of elementary equations for optimal power allocation. A threshold technique is developed to determine the number of beams that should be used over different SNR regions. This can be done, in advance, for a given channel covariance structure thereby facilitating optimal power allocation on a real time basis. Numerical results are presented for the illustration of the theory. ☆─────────────────────────────────────☆ fff (小溪) 于 (Wed May 21 09:01:13 2008) 提到: 主讲人简介： Q.T. Zhang received the B.Eng. from Tsinghua University, Beijing, and M.Eng. from South China University of Technology, Guangzhou,China, both in wireless communications, and the Ph.D. degree in electrical engineering from McMaster University, Hamilton, Ontario, Canada. After graduation from McMaster in 1986, he held a research position and Adjunct Assistant Professorship at the same institution. In January 1992, he joined the Spar Aerospace Ltd., Satellite and Communication Systems Division, Montreal, as a Senior Member of Technical Staff. At Spar Aerospace, he participated in the development and manufacturing of the Radar Satellite (Radarsat). He joined Ryerson Polytechnic University, Toronto in 1993 and became a Professor in 1999. In 1999, he took one-year sabbatical leave at the National University of Singapore, and is now a Professor with the City University of Hong Kong. His research interest is on transmission and reception over fading channels with current focus on wireless MIMO, distributed space-time systems, and cognitive radio. He was an Associate Editor for the IEEE Communications Letters} from 2000 to 2007, and a co-guest editor for EURASIP Journal on Advances in Signal Processing on the special issue of distributed space-time systems. He was one of the winners of best paper award on WCNC2008. ☆─────────────────────────────────────☆ alibupt (啊力) 于 (Wed May 21 09:02:45 2008) 提到: 顶 ☆─────────────────────────────────────☆ jinjing9611 (jinjing9611) 于 (Wed May 21 09:03:49 2008) 提到: ☆─────────────────────────────────────☆ fff (小溪) 于 (Wed May 21 09:03:54 2008) 提到: 可能第7场要连在第6场后面马上开始了，同一个教室，icc好像23号下午没有安排，好多教授都是23号来 ☆─────────────────────────────────────☆ nancywsh (nancy) 于 (Wed May 21 09:04:57 2008) 提到: ding ☆─────────────────────────────────────☆ Prisco (律师) 于 (Wed May 21 09:16:41 2008) 提到: 顶啊 ☆─────────────────────────────────────☆ dika (dika) 于 (Wed May 21 09:49:15 2008) 提到: 顶 ☆─────────────────────────────────────☆ iamalive (北邮鲨鱼帮之活蹦乱跳鱼) 于 (Wed May 21 09:49:56 2008) 提到: 我顶 ☆─────────────────────────────────────☆ Saving (光明顶群英之资深潜水员) 于 (Wed May 21 09:50:34 2008) 提到: 支持【在 fff 的大作中提到: 】工程学院、信息工程学院等共同策划、组织ICC 2008北邮系列学术讲座，将陆续邀请到多位与会资深专家来我校作精彩的学术报告。本次活动是由电信院WT&T实验室发起，同时得到电信工程学院、信息工程学院等多个实验室的积极响应。 ☆─────────────────────────────────────☆ EVDO (EVDO) 于 (Wed May 21 09:58:56 2008) 提到: 不错，bd ☆─────────────────────────────────────☆ loulou (loulou) 于 (Wed May 21 10:03:40 2008) 提到: 顶 ☆─────────────────────────────────────☆ appleeden (安安) 于 (Wed May 21 10:33:19 2008) 提到: ding ☆─────────────────────────────────────☆ Yvonnay (Yvon*管理生活*) 于 (Wed May 21 10:49:12 2008) 提到: 热情一顶～ ☆─────────────────────────────────────☆ ltdxx (伐木丁丁 ) 于 (Wed May 21 11:01:51 2008) 提到: 很支持的 ☆─────────────────────────────────────☆ Alger (霜之哀伤) 于 (Wed May 21 11:55:02 2008) 提到: 赞！ ☆─────────────────────────────────────☆ rosyclouds (残剑飞雪) 于 (Wed May 21 12:32:02 2008) 提到: ding ☆─────────────────────────────────────☆ dcc1031 (太子换狸猫@一夜情寝室) 于 (Wed May 21 15:08:26 2008) 提到: 【在 fff 的大作中提到: 】工程学院、信息工程学院等共同策划、组织ICC 2008北邮系列学术讲座，将陆续邀请到多位与会资深专家来我校作精彩的学术报告。本次活动是由电信院WT&T实验室发起，同时得到电信工程学院、信息工程学院等多个实验室的积极响应。这方面的问题最近几年论文无敌多，他要说的这个题目叫statistical feedback,不知道是否指的是反馈信道响应的二阶矩，还有correlated MIMO Rayleigh用的是啥模型，还有相关性和反馈的内容是如何体现的。第七场内容是啥？？？ ☆─────────────────────────────────────☆ darling (洞庭小妖) 于 (Wed May 21 17:45:20 2008) 提到: 顶则个 ☆─────────────────────────────────────☆ puzzlebyr (puzzle_1985) 于 (Wed May 21 19:15:57 2008) 提到: 自己实验室的~ 顶一个先 ☆─────────────────────────────────────☆ prairiewolf (prairiewolf) 于 (Wed May 21 19:26:53 2008) 提到: bd ☆─────────────────────────────────────☆ yunnan47 (mickey_lee) 于 (Wed May 21 19:42:31 2008) 提到: ding~~ ☆─────────────────────────────────────☆ puzzlebyr (puzzle_1985) 于 (Wed May 21 20:04:54 2008) 提到: 再顶 ☆─────────────────────────────────────☆ newzq0252092 (大秋) 于 (Wed May 21 20:49:05 2008) 提到: 顶 ☆─────────────────────────────────────☆ snowsunny (snowsunny) 于 (Thu May 22 11:21:53 2008) 提到: up ☆─────────────────────────────────────☆ puzzlebyr (puzzle_1985) 于 (Thu May 22 15:13:58 2008) 提到: 顶
