Abstract :
The paper presents some preliminary results of experimental studies of space-division-multiple-access (SDMA) systems for wireless communications. Although SDMA schemes and its potential capability of increasing channel capacity have been studied by a number of researchers, most of these studies are based on theoretical analyses and computer simulations. Very few real RF or microwave experiments have been conducted to study the channel propagation associated with multiple antennas and to validate various theoretical results and system designs about SDMA. The purpose of the paper is to present preliminary experimental results, based on which the authors discuss the feasibility of proposed SDMA systems and propose some new and feasible SDMA implementation schemes to increase channel capacity and improve system performance
