Impact of Interference on the System Performance of Wimax Relay 802.16j With Sectoring
The WiMAX Forum has proposed the standard 802.16j using relays in order to extend cell coverage at low cost. Moreover, the throughput of the user could be enhanced by using a better link connection. In a previous study, the authors proposed a Wimax Relay 802.16j model with sectoring technique to enhance the system performance. It resulted in a significant increase in terms of spectrum efficiency and throughput at the base station. However, in that study they assumed that there was no interference between base stations and relay stations and they compared the system of their model to the other models by analyzing the system performance in an isolated cell.
