Abstract :
In this paper the performance of mobile WiMAX system in terms of downlink distributed (FUSC, PUSC) and adjacent (AMC) subcarrier permutation modes is investigated using simulation under various modulation and coding schemes (link speeds). The results are expressed in terms of the maximum achievable throughput and operating distance in vehicular multipath fading channel (ITU-R Vehicular A at 60km/h and 120km/h speeds) under the Quality of Service (QoS) requirements for Video on Demand (VoD) application, which is an application for multimedia services. The results show differences in Packet Error Rate (PER) performance at various modulation and coding schemes for the three subcarrier permutation modes (FUSC, PUSC and AMC). This differences in performance are exploited in the present work to show the best threshold Signal to Noise Ratio SNR to switch from link speed to another link speed in terms of throughput and operating distance.
