The base station antenna array system output SNIR determination for different spatial channel models

We consider the application of some adaptive algorithms for antenna array beam steering. Three spatial channel models ( Lee´s model, Gaussian angle of arrival model and discrete uniform distribution angle of arrival model) and 12-element antenna array are simulated. The antenna array beam steering is performed by using the adaptive algorithms: least mean square (LMS), least mean fourth (LMF), recursive least square (RLS) and sample matrix inversion (SMI). The output antenna array SNIR is analyzed and plotted relating to the angular width and the iteration number of the adaptive algorithms.
