学术讲座通知应信息与通信工程学院周正教授邀请，葡萄牙阿威罗大学的Professor Paulo J. S. G. Ferreira和Professor Jose M. N. Vieira将于7月5日访问北邮泛网无线通信教育部重点实验室，并作精彩学术报告。欢迎我校师生踊跃参加。题目1：Topics in sampling: historical, mathematical and engineering 主讲人：Professor Paulo J. S. G. Ferreira (葡萄牙阿威罗大学) 题目2：Compressed Sensing and Applications 主讲人：Professor Jose M. N. Vieira (葡萄牙阿威罗大学) 时间：2010年7月5日（星期一）上午9：30 地点：校办公楼501报告厅讲座内容简介： Topics in sampling: historical, mathematical and engineering：This is a three part talk, each part lasting for 10 to 15 minutes. It covers different topics in the hope of making it interesting to mathematicians and engineers. This is collaborative research and the different co-authors (nine authors from several countries) are acknowledged separately. Part 1 is historical: it discusses the history of sampling and an effort for implementing sampling in the 1930s. Part 2 is mathematical an addresses sampling, its role in mathematical analysis and the nature and role of equivalence groupings built around sampling theorems. Part 3 briefly describes integrate-and-fire converters, their potential and some of the open problems that they pose. Compressed Sensing and Applications：Compressed Sensing or Compressive Sampling (CS) is a sampling strategy that uses linear combinations of a signal combined with an optimization process to recover the original signal. Instead of taking advantage of the bandlimitedness it takes advantage of its compressibility. In this talk we introduce the basic notions of CS and the algorithms to reconstruct the original signal from the linear combinations. A short overview of some possible applications is also given. 此报告为前沿讲座，欢迎全校师生踊跃参加。校学术委员会泛网无线通信教育部重点实验室 2010年7月1日 -------------------------------------------------------------------------------- 返回
