Abstract
MIMO systems based on lens antennas are very promising for 5G networks. Some scientific papers have already been devoted to the problem of channel estimation in MIMO systems based on hemispherical lens antennas. However, Luneburg multipath lens antennas are also a promising type of lens antennas for 5G networks. This paper presents the results of channel estimation features research in 5G MIMO-OFDM systems with Luneburg lens antennas. The research results of six different interpolation methods effectiveness for estimating the channel characteristics based on pilot signals and MIMO detectors (Neumann, conjugate gradients, MMSE) in a 5G cellular communication system of the millimeter range are presented.
