Optimal precoding for orthogonalized spatial multiplexing in closed-loop MIMO systems
In this paper, we propose a new precoding algorithm for orthogonalized spatial multiplexing (OSM) systems over flatfading multiple-input multiple-output (MIMO) channels. The OSM sc...

OS-aware tuning: improving instruction cache energy efficiency on system workloads
Low power has been considered as an important issue in instruction cache (I-cache) designs. Several studies have shown that the I-cache can be tuned to reduce power. These techniq...
