Optimizing Training-Based MIMO Systems: How Much Time is Needed for Actual Transmission?
—We study the design of training-based multiple-input multiple-output systems in two block-wise transmission schemes. The conventional transmission scheme has a fixed amount of ...

Optimal Control in Large Stochastic Multi-agent Systems
Abstract. We study optimal control in large stochastic multi-agent systems in continuous space and time. We consider multi-agent systems where agents have independent dynamics with...

An Accelerated Datapath Width Optimization Scheme for Area Reduction of Embedded Systems
Datapath width optimization is very effective for reducing the area of a custom-made embedded system. The trivial way of optimization is to iteratively customize, evaluate, and r...
