Abstract
System and methodologies are provided herein for rate, power and precoder adaptation for slow fading MIMO communication channels with noisy limited feedback. To optimize a rate of successful information delivery from a wireless transmitter to a wireless receiver and to provide robustness to channel noise, a joint design and optimization technique is utilized to provide optimal power, rate, and precoding adaptation policies for use by a wireless transmitter and an optimal feedback scheme and index assignment mapping for use by a wireless receiver. Additionally, various optimization and design techniques described herein are performed using a low-complexity online adaptation coupled with an offline optimization design.
