Abstract

Hybrid precoding combines the advantages of analogue and digital techniques and has become the preferred precoding method for achieving a balance between high performance and cost-effectiveness in large-scale MIMO systems by simplifying hardware requirements and reducing energy consumption.In this study, a novel hybrid precoding method based on Joint Space Division Multiplexing (JSDM) and Successive Interference Cancellation (SIC) techniques is proposed for multi-user 3D MIMO systems.User grouping and statistical information based analogue pre-coding using JSDM is firstly used to form a suppression of major interferences, whereas SIC further optimises the digital pre-coded joint combining matrix to finely tune the data stream for each user by sequentially detecting and removing interference from the decoded signals. The experimental results show that the hybrid precoding scheme based on JSDM and SIC can significantly improve the spectral efficiency and BER performance in multi-user scenarios.
