9405102 Proakis This research will investigate and demonstrate solutions to known problems in indoor wireless systems. Solutions will be demonstrated analytically and experimentally, at a wireless multiple-access testbed under development at Northeastern University. Both the baseband transmitter files and acquisition attributes for this testbed are fully programmable, and the researcher can demonstrate novel transmission and reception techniques on actual radio frequency data directly in the Matlab environment. For the duration of this grant, the investigator will address low-cost antenna diversity techniques, low-complexity demodulation schemes for dynamic fading channels, the localization of transmitters within the antenna field, the prediction of deep fades via localization, and the prediction and cancellation of intrabuilding interference (from office equipment and other wireless transmitters). During the 24-month period, the research associate will specify novel multiuser communication system architectures with application to hospital patient monitoring and to general indoor wireless networks. Broader applications will also be devised, including the development and implementation of multiuser detection algorithms, wavelet-based signal design, and channel waveform design for asynchronous multiple-access systems. ***

9405102 Proakis这项研究将调查并演示室内无线系统中已知问题的解决方案。解决方案将在东北大学正在开发的无线多址测试台上进行分析和实验演示。该试验台的基带发射机文件和采集属性都是完全可编程的，研究人员可以直接在Matlab环境中对实际射频数据演示新的发射和接收技术。在此拨款期间，研究者将研究低成本天线分集技术、动态衰落信道的低复杂度解调方案、天线场内发射机的定位、通过定位预测深衰落、以及预测和消除建筑物内干扰（来自办公设备和其他无线发射机）。在24个月的时间里，研究助理将指定新的多用户通信系统架构，应用于医院病人监测和一般室内无线网络。还将设计更广泛的应用，包括多用户检测算法的开发和实现，基于小波的信号设计，以及异步多址系统的信道波形设计。＊＊＊
