The Tri-Hybrid MIMO Architecture
Robert W. Heath, Joseph Carlson, Nitish Vikas Deshpande +3
We present an evolution of multiple-input multiple-output (MIMO) wireless communications known as the tri-hybrid MIMO architecture. In this framework, the traditional operations of…

Hierarchical Codebook Design with Dynamic Metasurface Antennas for Energy-Efficient Arrays
Joseph Carlson, Miguel R. Castellanos, Robert W. Heath
Dynamic metasurface antennas (DMA) provide a solution to form compact, cost-effective, energy-efficient multiple-input-multiple output (MIMO) arrays. In this paper, we implement a…
