EIA-9977387Costello, Daniel J.Collins, OliverUniversity of Notre DameMRI: Acquisition of Instrumentation for an Experimental Radio Facility in Support of Wireless Digital Communications ResearchA team of researchers proposes to construct a facility to provide two-way digital communications capabilities which will consists of two base stations, a number of mobile units and all test equipment necessary to effect narrowband transmission over a geographical area of several square miles. This facility will provide a resource that is rare in academia - an actual operational testbed for research into the algorithms and devices that make wireless digital communications possible. Some of the issues that will be investigated with this facility include: (i) the effectiveness of various error control schemes in a wireless environment, (ii) the design and testing of novel communication devices, circuits and architectures based on compound semiconductor technology, (iii) the ''synergy'' arising from use of spatial diversity in conjunction with coded modulation and interference mitigation, and (iv) experimental testing of proposed new techniques for anticipating the ''deep fades'' that afflict mobile communications.

EIA-9977387Costello、Daniel J.Collins、奥利弗圣母大学 MRI：采购用于支持无线数字通信研究的实验无线电设施的仪器一个研究小组提议建造一个提供双向数字通信功能的设施，该设施将包括两个基站、多个移动单元以及在几平方英里的地理区域内实现窄带传输所需的所有测试设备。 该设施将提供学术界罕见的资源——一个用于研究使无线数字通信成为可能的算法和设备的实际操作测试平台。 该设施将研究的一些问题包括：（i）无线环境中各种错误控制方案的有效性，（ii）基于化合物半导体技术的新型通信设备、电路和架构的设计和测试，（iii）空间分集与编码调制和干扰抑制相结合使用所产生的“协同作用”，以及（iv）对拟议的新方案的实验测试 预测影响移动通信的“深度衰落”的技术。
