Visualization and analysis of the OFDMA downlink capacity region


S. Görtzen, A. Schmeink,


        In this paper we introduce a symmetrybased approach to visualize the OFDMA downlink capacity region and its convex hull. These sets are compared to numerically analyse the fact that the capacity region of an OFDMA system with an infinite number of subcarriers is convex. We believe that this approach offers a unique perspective on the structural properties of the capacity region which in turn might spawn new ideas concerning the complex problem of allocating subcarriers in order to maximize weighted sum rates (WSRmax problem).
