On the Performance of Adaptive Smart Antenna Systems in Multipath Environments

Abstract- In this paper, we analyze the performance of an adaptive smart antenna system (SAS) in mul-tipath environments. Experiments were performed to validate for the proposed method [2] for single user case. Multiple user case is also considered for several wireless communication environments, with code divi-sion multiple access (CDMA). Throughout the com-puter simulations, the probability of bit errors are pre-sented for the systems using the singular value decom-position (SVD) method and the proposed method. 1 Introdunction Recently, there has been research regarding how adap-tive SASs in mobile communications increase system capacity and cell coverage [1] [5]. SASs exploit the spatial diversity of multiple users by employing an an
