Wireless communication has enjoyed explosive growth over  the past decade.  As demands for increased capacity and  quality grow, improved methods for harnessing the multipath wireless channel must be developed.  The use of adaptive  antenna arrays is one area that shows promise for improving capacity of wireless systems and providing improved safety  through position location capabilities.  These arrays can  be used for interference rejection through spatial  filtering, position location through direction finding  measurements, and developing improved channel models  through angle of arrival channel sounding measurements.   This thesis provides an overview of the technical  challenges involved in position location of wireless users  and details the hardware development of a multi-sensor  testbed at the Mobile and Portable Radio Research Group  at Virginia Tech.  This testbed is to be used for position  location experiments as well as a host of other adaptive  signal processing applications.
