Sobelman 讲座地点：教三136 讲座时间：6月12号下午2：00-3：30 交流会时间：6月12号下午3：30-4：30（即讲座结束后立刻进行）交流会地点: 教一116 本讲座为前沿讲座，可盖章！！今年是IEEE成立125周年纪念年，IEEE组织了IEEE杰出讲师系列讲座计划（DLP lecture- Distinguished Lecturer Program）。应IEEE 电路与系统北京分会与光通信与光电子学研究院、IEEE高级会员张晓光教授邀请，美国明尼苏达大学教授、IEEE杰出讲师G.Sobelman博士（中文名字苏杰睿）来北邮进行IEEE杰出讲师系列讲座计划之一——北京邮电大学IEEE杰出讲师讲座。另外在IEEE北邮学生分会的邀请下，Sobelman教授在讲座之后将和北邮的IEEE协会会员以及广大同学进行一次座谈会，地点在教一116。届时座谈会分为两个部分：首先由Sobelman 和大家分享他在学术界和工业界的发展历程，以及工作的经验和感想。接下来会有半个小时左右的自由交流时间，大家到时候可以在学术研究等方面与Sobelman 教授进行探讨交流。 Abstract of Lecture Flexibility and efficiency will be key design requirements for future communications transceivers. Systems must be reconfigurable and adaptable in order to minimize power and maximize bandwidth as environmental conditions and user requirements change. This lecture will present architectures and design techniques to achieve these goals for Ultra Wideband (UWB), multiple antenna (MIMO) and Cognitive Radio systems. We will begin with a class of UWB systems based on Orthogonal Frequency Division Multiplexing (OFDM). The standard approach uses large FFTs, which can require a significant amount of hardware resources. An attractive design alternative known as Pulsed-OFDM UWB can achieve the same system-level performance while requiring less hardware and power. We will describe flexible architectures to implement these OFDM-based systems. In addition, we will also present a hardware model of the UWB channel in order to achieve faster system-level verification. The performance of MIMO systems scales with the number of antennas, so extremely high throuphputs are possible. In practice, however, the design complexity also increases rapidly with the number of antennas, so it is crucial to develop efficient implementations for such systems. We will describe a promising approach based on the Geometric Mean Decomposition (GMD) and we will give throughput and design complexity results for a range of MIMO systems. Cognitive radio seeks to take advantage of the local spectrum conditions in order to maximize throughput whenever possible. This requires a flexible platform in which many aspects of the system can be reconfigured dynamically. For example, the parameters associated with digital filters, FFTs and interleavers may have to be adjusted in order to implement a new data rate, modulation scheme or detection algorithm. In addition, the connections between various functional units may have to be altered to implement different data flow requirements. Programmable functional units and network-on-chip architectures will be described to address these issues. Brief Biography Gerald E.
