Hybrid Precoding in mmWave and massive MIMO Systems
Designing hybrid analog/digital precoders/combiners is challenging mainly because of the coupling between the analog and digital precoders. In our group, we investigated the hybrid precoding/combining design problem for single-user/multi-user mmWave and low-frequency massive MIMO systems. Recently, we investigated the hybrid precoders design for wideband frequency selective mmWave systems. Our group also proposed and evaluated the performance of different hybrid precoding architectures, addressing practical aspects like the implementation of the analog precoders using phase shifters or switches.
