Une expérience de propagation sur un canal réel est menée pour confirmer l'efficacité de la technique de formation de faisceaux dans le domaine temporel (TDBF) en une seule pression que nous avons proposée dans des travaux précédents. Cette technique offre une formation de faisceau simple pour la liaison sans fil appliquée à la bande d'ondes millimétriques à entrées multiples et sorties multiples (MIMO) et prend ainsi en charge le déploiement rapide de petites cellules de communications mobiles (1G) de cinquième génération. Cet article détaille les expériences de propagation dans la bande 5 GHz et les évaluations des caractéristiques du TDBF à 75 prise telles que déterminées à partir de mesures de canal réelles. Les résultats montrent que le gain du réseau TDBF en 1 prise est presque égal à la valeur de combinaison de rapport maximal dans le domaine fréquentiel (MRC), ce qui constitue un traitement idéal ; la différence est inférieure à 1 dB. De plus, le TDBF à 0.5 prise peut améliorer le rapport puissance signal/interférence (SIR) d'environ 1 % lorsque le multiplexage par répartition spatiale (SDM) est effectué en supposant les niveaux existants d'erreur d'estimation de canal.

Abstract: A propagation experiment on an actual channel is conducted to confirm the effectiveness of the 1-tap time domain beamforming (TDBF) technique we proposed in previous work. This technique offers simple beamforming for the millimeter waveband massive multiple-input multiple-output (MIMO) applied wireless backhaul and so supports the rapid deployment of fifth generation mobile communications (5G) small cells. This paper details propagation experiments in the 75GHz band and the characteristics evaluations of 1-tap TDBF as determined from actual channel measurements. The results show that 1-tap TDBF array gain nearly equals the frequency domain maximal ratio combining (MRC) value, which is ideal processing; the difference is within 0.5dB. In addition, 1-tap TDBF can improve on the signal-to-interference power ratio (SIR) by about 13% when space division multiplexing (SDM) is performed assuming existing levels of channel estimation error.
