Visible light communication (VLC) has attracted much attention in the research of sixth-generation (6G) systems. Furthermore

channel modeling is the foundation for designing efficient and robust VLC systems. In this paper

we present extensive VLC channel measurement campaigns in indoor environments

i.e.

an office and a corridor. Based on the measured data

the large-scale fading characteristics and multipath-related characteristics

including omnidirectional optical path loss (OPL)

K-factor

power angular spectrum (PAS)

angle spread (AS)

and clustering characteristics

are analyzed and modeled through a statistical method. Based on the extracted statistics of the above-mentioned channel characteristics

we propose a statistical spatial channel model (SSCM) capable of modeling multipath in the spatial domain. Furthermore

the simulated statistics of the proposed model are compared with the measured statistics. For instance

in the office

the simulated path loss exponent (PLE) and the measured PLE are 1.96 and 1.97

respectively. And

the simulated medians of AS and measured medians of AS are $25.94^\circ$ and $24.84^\circ$

respectively. Generally

the fact that the simulated results fit well with measured results has demonstrated the accuracy of our SSCM.
