Summary: Communication over millimeter wave (mmWave) frequencies is a key component of the fifth-generation (5G) cellular networks due to the large bandwidth available at mmWave bands. However, the mmWave frequencies face severe propagation loss, which includes path loss, penetration loss, and rain fading. Thanks to the short wavelength of mmWave bands, large antenna arrays (32 to 256 elements are common) can be mounted at the transceivers to combat the propagation loss. The array sizes are typical of a massive MIMO communication system, which makes fully digital beamforming difficult to implement due to high power consumption and hardware cost. This motivates the development of hybrid beamforming due to its versatile tradeoff between implementation cost (including hardware cost and power consumption) and system performance. However, due to the non-convex constraints on hardware (phase shifters), finding the global optima for hybrid beamforming design is often intractable. In this seminar, we will introduce the basic principle of beamforming at the beginning then focus on hybrid beamforming design for narrowband single-user mmWave cellular communications.
