Abstract :
The increasing demand for personal mobile communications systems has led to heightened intensity of research in the field of adaptive base station antennas, specifically in the development of robust adaptive algorithms and structures. In this study, we examine the different spatial-temporal equalisation schemes using the constant modulus algorithm (CMA) on a uniformly spaced linear array and introduce a variant structure wherein equalisation is performed on beam-space data, as opposed to element-space. From simulations performed, two-dimensional equalisation on beam space data is seen to produce superior results in terms of final convergence and speed
