MMSE Adaptive Beam Forming Algorithms for WCDMA Mobile Communication System

Abstract: Smart antenna technologies are very important for the system implementation. Smart Antennas serve different users by radiating narrow beams. The same frequency can be reused even if the users are in the same cell or the users are well separated. Thus, the capacity of the system is increased by implementing this additional intra cell reuse. This paper discusses algorithms developed for smart antenna applications to WCDMA. The Minimum mean-square error (MMSE) Algorithm is an adaptive beam forming algorithms used in smart antennas.

Keywords: Minimum mean-square error (MMSE), Maximum likelihood (ML), Adaptive beam forming, smart antenna.
