MIMO Channel Measurement in Heterogeneous Networks

Abstract

Cutting-edge technologies focusing on optical efficiency, data rates, and transmission power efficiency are propelling the evolution of multiple-input-multiple-output (MIMO) systems. These innovations facilitate higher aggregation rates, particularly beneficial in large MIMO generation environments. However, the fixed nature of MIMO results in a smaller channel shape in the spatial domain, limiting dynamic adoption in various 2D channels. Despite this constraint, the distinctive channel characteristics of MIMO present opportunities for significant improvements in 5G network capacity. This study explores and compares the channel nature of MIMO, shedding light on its potential to optimize network performance in heterogeneous environments, marking a noteworthy stride in the pursuit of enhanced wireless communication technologies.
