Abstract :
This paper develops a feedforward approach to data rate control in wireless networks. The development is based on designing an optimal, but non-causal, controller and its subsequent "causification", which results in a practical, implementable controller, driven by an estimate of the bit error probability. It is shown that this controller leads to a minimum of 5%-85% increase in average throughput without additional power utilization, as compared with fixed data rate operation
