MRI: Acquisition of Instrumentation for an Experimental Radio Facility in Support of Wireless Digital Communications Research

costello, Daniel J.Collins， OliverUniversity of Notre damri：为支持无线数字通信研究的实验无线电设施购置仪器一组研究人员建议建造一个设施，以提供双向数字通信能力，该设施将由两个基站、一些移动单元和所有必要的测试设备组成，以在几平方英里的地理区域内实现窄带传输。该设施将为研究使无线数字通信成为可能的算法和设备提供学术界罕见的资源——一个实际的操作测试平台。该设施将调查的一些问题包括：（一）无线环境中各种误差控制方案的有效性；（二）基于复合半导体技术的新型通信设备、电路和架构的设计和测试；（三）结合使用空间分集与编码调制和干扰缓解所产生的“协同效应”；以及（四）对拟议的新技术进行实验测试，以预测影响移动通信的“深衰减”。

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.
