Hybrid beamforming for 5G millimeter-wave multi-cell networks
Multi-cell wireless systems usually suffer both intracell and inter-cell interference, which can be mitigated via coordinated multipoint (CoMP) techniques. Previous works on multi-cell analysis for the microwave band generally consider fully digital beamforming that requires a complete radio-frequency chain behind each antenna, which is less practical for millimeterwave (mmWave) systems where large amounts of antennas are necessary to provide sufficient beamforming gain and to enable transmissio
