Abstract
In this paper, we propose an imaging angle diversity receiver (ADR) that can support multi-Gb/s data rates for 6G optical wireless networks. We derive accurate mathematical expressions for the optical gain and field-of-view (FOV) of the imaging receiver in terms of its various geometrical parameters. Additionally, we identify the design tradeoffs and formulate a non-convex optimisation problem to maximise the data rate under the required FOV constraint. We also propose a low-complexity optimal solution for the optimisation problem, based on which we demonstrate the design of an imaging ADR with a $10^{\circ}$ half-angle FOV, providing a data rate of 12 Gb/s for a 3 m link distance.
