Abstract :
IEEE 802.16j emerged as a standard in the middle of 2009, specifying the procedure of supporting Mobile Multi-hop Relay (MMR) networks. Co-channel interference is considered as a parameter to analyze the performance of IEEE 802.16j based relay networks. Frequency reuse technique is a way to improve the frequency utilization. Since the same frequency band is used by Relay stations and Base Station, co-channel interference within a cell becomes a major problem. This degrades the uniform Quality of Service (QoS) within the cell. As an effective way to analyze the co-channel interference, signals are retransmitted again by the transmitting stations. From the simulation results it is observed that when the number of mobile stations is increased, signal to interference ratio (SIR) is improved.
