Abstract :
We present a practical link adaptation algorithm for MIMO-OFDM systems. The proposed solution is based on sounding the channel periodically and choosing the optimal mode that will maximize the throughput or energy efficiency while satisfying the application´s quality of service (QoS) requirements. In addition, we address practical problems such as computational complexity of the algorithm and determination of sounding period, by novel closed form formulations and iterative algorithms.
