Dans cet article, nous étudions la conception optimale de systèmes multi-utilisateurs à entrée et sortie multiples (LOS MIMO) multi-utilisateurs à ondes millimétriques (mmWave) utilisant des réseaux hybrides de sous-réseaux basés sur un schéma de précodage et de combinaison de diagonalisation de blocs hybrides (BD). . En introduisant un modèle de canal géométrique 3D général, les produits de séparation de sous-réseaux optimaux de l'émetteur et du récepteur pour maximiser le débit somme sont conçus en termes de deux configurations régulières de sous-réseaux adjacents et de sous-réseaux entrelacés pour différents utilisateurs, respectivement. Nous analysons la sensibilité des paramètres de conception optimaux sur les performances en termes de facteur d'écart et dérivons des expressions pour les valeurs propres de la matrice de canal LOS MIMO équivalente multi-utilisateur, qui sont également valables pour une conception non optimale. Les résultats de la simulation montrent que les sous-réseaux entrelacés peuvent prendre en charge une communication à plus longue distance que les sous-réseaux adjacents, compte tenu du déploiement approprié du sous-réseau fixe.

Abstract: In this paper, we investigate optimal design of millimeter-wave (mmWave) multiuser line-of-sight multiple-input-multiple-output (LOS MIMO) systems using hybrid arrays of subarrays based on hybrid block diagonalization (BD) precoding and combining scheme. By introducing a general 3D geometric channel model, the optimal subarray separation products of the transmitter and receiver for maximizing sum-rate is designed in terms of two regular configurations of adjacent subarrays and interleaved subarrays for different users, respectively. We analyze the sensitivity of the optimal design parameters on performance in terms of a deviation factor, and derive expressions for the eigenvalues of the multiuser equivalent LOS MIMO channel matrix, which are also valid for non-optimal design. Simulation results show that the interleaved subarrays can support longer distance communication than the adjacent subarrays given the appropriate fixed subarray deployment.
