The goal of this research is to expand our knowledge of communication theory, information theory, and signal processing, and to make an immediate impact in practical wireless communication systems and networks. The research builds upon the general theory and code design strategy for space-time coding. The mathematical methods, algorithms, and concepts developed in this research is applicable and initiates new activities in many different areas of communications and applied mathematics. These areas include modem design, equalization, beam-forming, linear algebra, and soon. Of course, the immediate impacts are in increasing the data rates of wireless communication systems as well as advancing our understanding of the behavior of multiple-input multiple-outputchannels.Currently, there is a fundamental theoretical limit which prohibits us from designing full-rate orthogonal space-time block codes for more than two transmit antennas. Also, the available codes have not achieved the best performance claimed by information theory, so there exists a gap between what is possible, and the state of codes today. We seek to eliminate this gap by designing new classes of codes that provide full diversity, high rate, small complexity, high performance and mathematically interesting structures.

这项研究的目标是扩展我们在通信理论、信息论和信号处理方面的知识，并对实际的无线通信系统和网络产生直接影响。该研究建立在空时编码的一般理论和代码设计策略的基础上。 本研究中开发的数学方法、算法和概念适用，并在通信和应用数学的许多不同领域发起了新的活动。这些领域包括现代设计、均衡、波束形成、线性代数等等。当然，直接的影响是提高无线通信系统的数据速率以及增进我们对多输入多输出通道行为的理解。目前，存在一个基本的理论限制，阻止我们设计全速率正交用于两个以上发射天线的空时分组码。 此外，现有的代码尚未达到信息论所声称的最佳性能，因此可能的代码与当今的代码状态之间存在差距。我们寻求通过设计新类别的代码来消除这一差距，这些代码提供完全多样性、高速率、低复杂性、高性能和数学上有趣的结构。
