Although VLC has significant advantages over RF systems (not being affected by electromagnetic interference (EMI), having a wide spectrum range, energy efficiency, etc.), it also has its own problems. One of these problems is the high correlation between channels in multiple-input multiple-output (MIMO) structures. In this paper, a receiver structure with adjustable azimuth and elevation angles is proposed for MIMO VLC. The position of the receiver is determined by means of the receiver signal strength indicator (RSSI) parameter. The best angles were set for the MIMO receiver using positioning data. Repetition coding (RC) and spatial multiplexing (SMP) are used as MIMO schemes and bit error rate (BER) performance is obtained. The proposed receiver structure provides SNR gains at different locations in both schemes.trinfo:eu-repo/semantics/closedAccessGörünür Işık HaberleşmesiKonum BilgisiÇoklu-Girişli Çoklu-çıkışlı SistemlerVisible Light CommunicationPositioning DataMIMO SystemsConference Object10.1109/SIU59756.2023.10223907N/A
