Then, in Section 4.3, a more general antenna array with an arbitrary number of elements is considered, where element refers to an antenna in the array. The array response vector is introduced and related to the free-space single-path channel. Thereafter, it is shown that by also introducing...

Our goal now is to determine the response of the array when steered towards , when the weights are chosen using the equation above. Using the definition of the array factor, we can write: The above can be simplified by recalling the definition of the wave vector: Substituting the above ...
not included in the argument ofaULAsince the response for an ULA is independent of the elevation angle. In contrast, for a uniform planar array (UPA), which is composed ofNvandNhantenna elements in the vertical and horizontal directions, respectively, the array response vector is represented by...
Note that the received signal is no longer weighted by a steering vector toward a specific direction. Instead, the receiving array weights in this case are given by the complex conjugate of the channel response. Otherwise it is possible that multipath could make the received signal ...
The array response vector of the channel matrix reduces the computational complexity while retaining the optimality. Multi-layer classification will increase computational complexity. [166], 2019 Beamforming NN This paper uses simulation results to balance performance and computational complexity to achieve ...
Also, if some of the array response vector directions are very close to each other (much smaller separation than the main lobe width given by the array response vector), then multiple array response vectors can be assumed to be lumped together. Note that this discussion is not strict in a ...
