Abstract
The paper describes a system architecture and formulation of the Dynamic Subchannel Allocation problem in IEEE 802.16e networks. According to it, the DSA algorithm operates as an extension of a IEEE 802.16 time scheduler, trying to exploit the benefits of the OFDMA mode. Simulation results show a considerable improvement, compated to the legacy system, especially in terms of channel errors.
