Timing adjustment techniques to mitigate interference between multiple nodes in OFDMA mesh networks

We configure the multiple node interference (MNI) on OFDMA mesh networks and analyze the feature of this MNI as a closed form in terms of timing misalignment between multiple nodes. Based on our analysis, we propose some new timing adjustment techniques to mitigate MNI and verify the difference and superiority of the proposed techniques compared to the ones adopted by cellular OFDMA systems.
