Downlink Performance of Randomized OFDM Access
This paper is concerned with the downlink design of mobile communication systems using R-OFDM. A noticeable feature of R-OFDM is that the intra-cell interference is eliminated and the inter-cell interference can be approximately treated as Gaussian noise. Simulation results show that R-OFDM combined with space-time coded transmit diversity can achieve significant downlink capacity gain.
