MIMO Efficiency of a LTE Terminal Considering Realistic Antenna Models
نویسندگان
چکیده
This paper shows the influence of small coupled antenna arrays on the MIMO efficiency. Two different antenna models with varying antenna distances are investigated: dipoles and realistic terminal antennas. Two solutions to decouple the antennas are presented: 1) A parasitic element; 2) A hardware design of a matching network on a substrate which is the first implementation of a recent proposal in the literature. The resulting RF antenna properties are incorporated in the SCME channel model. The benefit in throughput is evaluated based on the information theoretic capacity and the throughput of a full-scale (coded) LTE link-level simulator.
