| Abstract: | The L2S interface methodology based on MI-ESM(mutual information effective SINR mapping)is analyzed.And the influence of coherence bandwidth of the channel on the interface complexity is studied.A method using coherence bandwidth of the channel to reduce the computation complexity is validated without obviously degrading the prediction accuracy. |
