This is the video for Lecture 2 in the course Multiple Antenna Communications at Linköping University and KTH. The lecture covers: the capacity of deterministic channels with multiple antennas at one side, the geometry behind maximum ratio processing, channel modeling for line-of-sight communications, beamwidth with uniform linear arrays.
