Content | 2004-06-29 IEEE C802.16e-04/230 2. The Solution Based on the analysis above, we propose the tile-based power control. The Base Station (BS) measures the average power of the tile, and then feeds back the adjustment command to the SS. The SS performs the power adjustment in digital domain. This accurate uplink power control eliminates the near-far effect in OFDMA system. 3. Performance In the simulation, Doppler frequency of 2 Hz is assumed. In this pedestrian case, radio channel varies slowly with time. Thus an instance of amplitude-frequency response in SUI5 channel model, as shown in Figure 2, is used in the simulation. In this instance, deep fading of more than 10dB exists. Fig.2 The instance of amplitude-frequency response for SUI5 Fig.3 The SIR versus frequency offset 3 |
