“…The authors in [ 31 ] have derived analytical expressions for the achievable rate of asymptotic ergodicities of the system under a zero-forcing (ZF) detector. The capacity of a 2 × 2 short-range LoS MIMO channel in three-dimensional space is studied and the spherical wave model (SWM) is used to model the corresponding channel with arbitrary antenna directions in three-dimensional space in [ 32 , 33 , 34 ].…”

The phase of the channel matrix elements has a significant impact on channel capacity in a mobile multiple-input multiple-output (MIMO) communication system, notably in line-of-sight (LoS) communication. In this paper, the general expression for the phase of the channel matrix at maximum channel capacity is determined. Moreover, the optimal antenna configuration of the 2 × 2 and 3 × 3 transceiver antenna array is realized for LoS communication, providing methods for n×n optimal antenna placement, which can be used in short-range LoS communication and non-scattering environment communication, such as coupling train communication and inter-satellite communication. Simulation results show that the 2 × 2 rectangular antenna array is more suitable for the communication of coupling trains, while the 3 × 3 circular arc antenna array is more suitable for virtual coupling trains according to antenna configurations. Moreover, the 2 × 2 antenna rectangular configuration proposed in this paper has reached the optimal channel in inter-satellite communication, which lays a foundation for the deployment of communication systems.

“…There are already many published works discussing the relation between the antenna correlation and the performance of multiple antenna systems in terms of ergodic capacity, outage capacity, bit error rate, and so forth [9][10][11][12][13][14]. However, to our knowledge, there are relatively few reports [15][16][17][18][19][20][21][22] on the relation between the multiple antenna system performance and the antenna layout, that is, the placement of the antenna elements. It is well known that, given the power azimuth spectrum (PAS) distribution and power elevation spectrum (PES) distribution [23], the performance of the multiantenna system is completely determined by the antenna spatial correlation matrix with its entries determined by the relative distance of the antenna elements.…”

“…In case of 2-dimensional (2D) deployment of multiple antenna elements and uniform PAS, it is reported [19,20] that the optimal antenna layout which can maximize MIMO capacity is the near circular array, but both of them considered a propagation model including PAS only. For short-range communications, [21] has investigated the optimal antenna placement of 2 × 2 MIMO taken into consideration the joint effects of path loss and phase difference. In [22], empirical results for the effects of antenna placement on vehicle-tovehicle link performance in vehicular ad hoc networks have been reported.…”

The performance of the multiantenna systems can be deeply affected by the antenna layout, that is, the placement of the antenna elements in a given area. This paper focuses on the optimal antenna layout which can maximize the ergodic capacity of a multiinput single-output (MISO) beamforming system. Since the optimization problem cannot be solved analytically, we use simulated annealing (SA) algorithm to search for the optimal antenna layout. The results show that the optimal antenna layout depends highly on the power azimuth spectrum (PAS) distribution and power elevation spectrum (PES) distribution. In the three-dimensional (3D) space uniformly scattering environment, the optimal antenna layout will locate the antenna elements on the surface of a sphere. When the scattering is concentrated in a two-dimensional (2D) plane, the circular layout is the optimal and finally, when there is no scattering (single plane wave), the optimal layout is the nonuniform linear array.
