“…Substituting ( 8)-( 12) into (13), the final formula of the increase rate of system capacity for the serving BS is In other words, the system capacity for the serving BS can be increased by 2.3%. As indicated by (14), the increase rate of system capacity is related to the number of beam adjustments and total time-frequency resources occupied in the beam management procedure. And the number of beam adjustments is related to factors such as the antenna configurations, the moving speed of the UE, the bandwidth, the SINR threshold of the UE, the applicable channel model, etc.…”

“…In general, beamforming can be seen as an adaptation problem, which can be implemented by an artificial neural network. In [14], a phase transmittance radial basis function neural network (RBF-NN) beamforming for static and dynamic channels was proposed. A beamforming neural network was designed to deal with the power minimization problem in [15].…”

“…Many DOA estimation methods based on neural networks have been developed in recent years to reduce the computational burden. References [12][13][14][15] using a convolutional neural network (CNN), references [16,17] using a support vector regression (SVR), reference [18] using a residual network, reference [19] using a fully connected neural network (FNN), reference [20] using a long short-term memory network, and references [21,22] using a radial basis function (RBF) achieve high accuracy DOA estimation. However, they can only be used in single-source scenarios, which may be extremely limited in practical applications.…”

“…Under channel linearity and time-invariance constraints, the conventional minimum mean squared error (MMSE) is the optimal linear operator for channel estimation under jointly Gaussian distributed random variables [4]. However, these constraints are unrealistic since even pedestrian channels are dynamic [5], and nonlinearities are common in power amplifiers [6]- [9]. In addition, as the MMSE channel estimation relies on covariance matrix inversions, the computational complexity is extremely expensive [10].…”
