LiFi for intra-satellite communication offers immense advantages like flexible AIT or reduced complexity (harness). However, high bandwidths and redundancies are equally required. Modulation methods that make use of the broad spectrum of light are (Color Space Based Modulations (CSBMs)). However, this requires precise knowledge of the transceivers and environments, as previous methods usually map to the CIE 1931 color scheme. But for intra-satellite communication, various assumptions can be made that favor the use of CSBM within the satellite. This paper presents an automated procedure that generates the symbols for CSBM. In order to ensure high reliability while using the entire color space for the symbols, a method based on cuboids is presented, which guarantees an overlap-free mapping between Transmit- and Signal-Space. In addition, the implementation of a Receiver based on an Field Programmable Gate Array (FPGA) is presented and real world measurements are conducted in detail to show the automatic symbol generation and the evaluation of symbol detection capabilities for communication.
