Adaptive beamforming arrays for smart antenna systems: a comprehensive performance study

A performance study of LMS adaptive beamformers has been carried out by investigating the effect of parameters related to both the beamforming array and signal environment. These parameters include number of beamformer array elements and their spacing, as well as the number of users and their angular separation. The performance study is essential for an optimal design of smart antenna systems utilizing LMS beamformers.
