An efficient algorithm for adaptive cell sectoring in CDMA systems

Cell sectorization is a promising method for improving the capacity of code division multiple access (CDMA) systems. It has been shown that the use of adaptive antenna arrays with dynamic cell sectoring is particularly suitable for non-uniformly distributed users. In this paper, we present a novel cluster-based sectoring algorithm for adaptive cell sectorization. The complexity of our algorithms, and more important, in a high-density case, it does not depend on the number of users in a cell. Extensive simulations show that the performance of our solution is comparable to the optimal solutions.
