Optical wireless communication (OWC) systems have been the subject of a\nsignificant amount of interest as they can be used in sixth generation (6G)\nwireless communication to provide high data rates and support multiple users\nsimultaneously. This paper investigates the impact of receiver orientation on\nresource allocation in optical wireless systems, using a wavelength division\nmultiple access (WDMA) scheme. Three different systems that have different\nreceiver orientations are examined in this work. Each of these systems\nconsiders 8 simultaneous users in two scenarios. WDMA is utilised to support\nmultiple users and is based on four wavelengths offered by Red, Yellow, Green\nand Blue (RYGB) LDs for each AP. An angle diversity receiver (ADR) is used in\neach system with different orientations. The optimised resource allocations in\nterms of wavelengths and access point (AP) is obtained by using a mixed-integer\nlinear programming (MILP) model. The channel bandwidth and SINR are determined\nin the two scenarios in all systems. The results show that a change in the\norientation of the receiver can affect the level of channel bandwidth and SINR.\nHowever, SINRs in both scenarios for all users are above the threshold (15.6\ndB). The SINR obtained can support t data rate of 5.7 Gbps in both scenarios in\nall systems.\n
