Millimeter waves is considered to be one of the solutions that will be used in the next generation communications to meet the increasing data demands due to the wide bandwidth provided. However, using these bands in the outdoors environment requires high directivity between the transmitter and the receiver to overcome the severe propagation losses. This paper presents the spectral efficiency analysis for the analog beamforming system as a solution to provide the required directivity. Under certain assumptions, an upper-bound and a closed form for the spectral efficiency is derived. The performance of three different search techniques is compared in the light of the proposed analysis. The simulation results confirm the derived analysis.
