Abstract:
The adaptive modulation technique is a promising solution to resolve the problem of spectrum scarcity. A key issue that defines the performance of adaptive modulation systems is the ability to find the optimum switching points between neighboring modulations. In this paper, we analyze the influence of the fading channel model in the optimum switching points, assuming a Nakagami-m fading model and both real and non-real-time traffic. Therefore, two criteria were considered to determine the optimum switching points: the maximum throughput criterion, for a real-time traffic scenario, and the delay criterion, for a non-real-time traffic scenario.
