IEEE802.16e WirelessMAN-OFDMA is expected to be a significant step in the evolution of communication technologies for the provision of broadband services to mobile users. Due to the large amount of parameters to be taken into account, from physical to upper layers, and the degrees of freedom left to manufacturers and operators, a simulation tool is almost mandatory along the path toward implementation...
In this paper, we propose a fast and efficient adaptive transmission algorithm for the mobile WiMAX system. In our algorithm, we select the position of the boundary between the downlink and uplink subframes, the positions of the service flows within the frame, the coding and modulation schemes, and the transmission power values. Our algorithm gains high spectral efficiency, satisfies quality-of-service...
