Abstract [en]

The paper investigates the performance of HIPER-LAN/2 (H/2) with sub-carrier based adaptive modulation, with respect to average throughput. The results obtained are compared with the case where the same modulation is used across all the sub-carriers as in the current H/2. We suggest a bit loading algorithm "Simple Rate Adaptive Algorithm" (SRA) based on the criteria of maximizing the throughput. Our work displays that this bit loading scheme improves the throughput compared to the existent H/2. The cost incurred is the complexity added by the adaptive modulation scheme. However, the total complexity of the system is decreased due to simplification in channel coding.
