    In orthogonal frequency division multiple access (OFD-MA) systems, soft frequency reuse (SFR) and distributed antenna system (DAS) are two effective techniques to avoid excessive inter-cell interference (ICI). To gain the advantages of both, in this letter, we build a new cell architecture by jointly taking DAS and SFR into consideration to achieve the goal of high and well-balanced capacity. Furthermore, to rectify the shortfall in the literature, the capacity and outage probability in the multi-cell environment are derived by taking the complete channel effects into account, including the path loss, shadowing and Rayleigh fading. Simulations verify the superior performance and exactness of the analytical results.
