What is SD-OFDMA: Enhancing Beamforming Performance about?

This document summarizes an opportunistic SD-OFDMA system that exploits temporal channel correlation. It proposes maintaining successful beams over multiple blocks by keeping beams that result in high scheduled sum-rates for the next block. This allows the system to schedule stationary users on the same beams while finding new beams for moving users. Extensive simulations showed this approach significantly improves cell throughput compared to a completely random beamforming scheme, especially at high system
