Abstract

The aim of this paper is to propose a way to optimize space diversity using lineal antenna arrays. Since the number of users in mobile communications is on the increase day by day, then it is important to improve the diversity of space. One solution to this problem is the Space-Division Multiple Access (SDMA) together with the concept of reuse of frequency based on the diversity of the space [1, 2]. Another possibility is the technique for solving lineal equations from a linear array of 8 elements to increase the size of the side lobes to optimize the space diversity; this process is proposed in this work. This procedure is compared with the factor of Dolph-Chebyshev.
