Abstract：

Medium-scale　or　large-scale　receive　antenna　array　with　digital　beamforming　can　be　employed　at　receiver　to　make　a　significant　interference　reduction　but　leads　to　expensive　cost　and　high　complexity　of　the　RF-chain　circuit.　To　deal　with　this　issue,　classic　analog-and-digital　beamforming　(ADB)　structure　was　proposed　in　the　literature　for　greatly　reducing　the　number　of　RF-chains.　Based　on　the　ADB　structure,　in　this　paper,　we　propose　a　robust　hybrid　ADB　scheme　to　resist　directions　of　arrival　(DOAs)　estimation　errors.　The　key　idea　of　our　scheme　is　to　employ　null　space　projection　(NSP)　in　the　analog　beamforming　domain　and　diagonal　loading　(DL)　method　in　digital　beamforming　domain.　The　simulation　results　show　that　the　proposed　scheme　performs　more　robustly,　and　moreover,　it　has　a　significant　improvement　on　the　receive　signal-to-interference-plus-noise　ratio　compared　to　NSP　ADB　scheme　and　DL　method.　©　2019　IEEE.
