This is an investigation of the adaptive and robust design of transmit signals for wireless transmission paths. The objective is to determine fundamental design methods that will allow reliable transmission at data rates several times faster than are presently achievable by adaptively contouring the transmit signals to match channel conditions. Time-varying and/or broadcast wireless transmission paths create special challenges for such adaptive transmission design that at present have not been solved. The project first studies transmission on fixed broadcast channels where feedback to the transmitter is not allowed and principles of robust signal design need to be derived to improve reliably transmitted data rates. Study then encompasses time-variation through both well known and new models for both broadcast and interactive time-varying (mobile) channels. The focus then shifts to generalization to multiuser coordinated transmission technologies. Extension and generalization of multi-tone waveforms which are very successful on wireline channels will be treated in these new and more challenging contexts.

这是一个调查的自适应和鲁棒性设计的发射信号的无线传输路径。 我们的目标是确定基本的设计方法，将允许可靠的数据传输速率比目前可实现的自适应轮廓的传输信号，以匹配信道条件的几倍。时变和/或广播无线传输路径对这种自适应传输设计产生了目前尚未解决的特殊挑战。 该项目首先研究在固定广播信道上的传输，其中不允许向发射机反馈，并且需要导出稳健信号设计的原则以提高可靠传输的数据速率。 研究，然后包括时间变化，通过众所周知的和新的模式，为广播和互动的时变（移动的）渠道。 然后，重点转移到多用户协调传输技术的推广。 在有线信道上非常成功的多音波形的扩展和推广将在这些新的和更具挑战性的背景下进行处理。
