Abstract


An IEEE 802.16j mobile WiMAX relay network is a next-generation mobile wireless broadband network that uses adaptive modulation coding. When a mobile station is shadowed by a building and thus has a bad-quality channel to the base station, such a relay design can help it achieve a higher throughput from/to the base station. It's not known what modulation zone QPSK½, QPSK¼ or 16QAM½ it should be from base station to relay station to achieve better throughput. Simulation was made with NCTUns. This paper analyzes which modulation zone is most efficient for relay stations to be deployed to achieve maximum network throughput. The number of subscriber stations impact to the network throughput with slot load in one frame and optimal relay stations number connected to one base station.
