  • Mar 2025
In this paper, we analyze the spectral efficiency for millimeter wave downlink with beam misalignment in urban macro scenario. For this purpose, we use a new approach based on the modified Shannon formula, which considers the propagation environment and antenna system coefficients. These factors are determined based on a multi-ellipsoidal propagati...

... spectral efficiency change versus the distance between the TX and RX. The comparison of the spectral efficiency change for the straight (i.e., α = 180° and β = 0°) and optimal (i.e., α = 180° and β = βmax) directions of the antenna beams is shown in Figure 6. The exemplary graphs are obtained assuming that the received signal level provides the SNR = 20 dB. ...
