0217549杜曼描述：该奖项是为了支持F.托尔加杜曼，电气工程系，亚利桑那州州立大学，滕佩，和阿里Ghrayeb博士，电气工程系在美国大学沙迦（澳大利亚）在沙迦，阿拉伯联合酋长国。 他们的研究涉及通过无线信道提供语音和数据服务。他们已经表明，对于在准静态衰落信道上的多发射多接收天线系统，在天线选择的情况下，不管潜在的空时码如何，分集阶数保持与全复杂度系统的分集阶数相同。 在这个项目中，他们计划：将他们早期的结果扩展到各种现实衰落信道模型上的空时码天线选择原则的情况（例如，块衰落、频率选择性衰落），当采用天线选择时进行性能分析并开发空时码的最佳码设计原理，考虑用于多个天线的turbo编码调制方案和低密度奇偶校验码的使用和设计并解决该上下文中的天线选择问题，研究了采用天线选择时的空时编码正交频分复用（OFDM）系统（将频率选择性衰落信道转换为频率平坦信道）。 这两位科学家从信道编码的角度研究了这个问题，并产生了一些初步的有希望的结果。 范围：在无线信道上传输语音和数据服务容易受到衰落和干扰等多种损害。 “多样性”是对抗衰落不利影响的最有效方法。 该研究旨在通过在接收机处采用天线选择来简化接收机复杂度，这导致复杂度的极大降低，因为仅需要一个接收机电路。 Duman博士目前正在他的研究所进行无线通信编码和无线通信智能天线的研究。 该项目将通过与Ghrayeb博士（AUS的约旦教员）的互动来帮助他目前的研究。 Ghrayeb将在夏季访问亚利桑那州州立大学，杜曼将在寒假访问沙迦的美国大学，继续该项目。 拟议的工作还将对亚利桑那州立大学和沙迦美国大学产生教育影响，并将导致两个机构的通信小组之间的持续合作。 研究结果将纳入这两个研究所的教材。

0217549DumanDescription: This award is for support of a cooperative project by Professor F. Tolga Duman, Department of Electrical Engineering, Arizona State University, Tempe, Arizona and Dr. Ali Ghrayeb, Department of Electrical Engineering at the American University of Sharjah (AUS) in Sharjah, United Arab Emirates. Their research deals with providing voice and data services over the wireless channel. They have shown that for a multiple transmit multiple receiver antenna system over a quasi-static fading channel, with antenna selection, regardless of the underlying space-time code, the diversity order remains the same as that of the full complexity system. In this project they plan to: extend their earlier results to the case of antenna selection principles for space-time codes over various realistic fading channel models (e.g., block fading, frequency selective fading), conduct performance analysis and develop optimal code design principles for space-time codes when antenna selection is employed, consider the use and design of turbo coded modulation schemes and low-density parity check codes for multiple antennas and address the antenna selection issues in that context, and study space-time coded orthogonal frequency division multiplexing (OFDM) systems (to convert the frequency selective fading channel into a frequency flat one) when antenna selection is employed. The two scientists have studied the problem from a channel coding perspective and produced some initial promising results. Scope: Transmitting voice and data services over the wireless channel is prone to several impairments such as fading and interference. "Diversity" is a most effective way of combating the adverse effects of fading. The research seeks to simplify the receiver complexity by employing antenna selection at the receiver that results in a great reduction in complexity, as only one receiver circuit is needed. Dr. Duman is presently carrying out research at his institute on coding for wireless communications and on smart antennas for wireless communications. This project will help his current research through the interaction with Dr. Ghrayeb (a Jordanian faculty member at AUS). Ghrayeb will visit Arizona State University during summers and Duman will visit the American University in Sharjah during winter break to continue the project. The proposed work will also have an educational impact both at ASU and the American University of Sharjah, and will result in a continued collaboration between the communications groups of the two institutions. The research results will be incorporated in educational material at both institutes.
