Channel modeling and characterization for VLC indoor transmission systems based on MMC ray tracing method

Channel modeling and characterization for VLC indoor transmission systems based on MMC ray tracing methodThe influence of transmission channel is one of the most important factors, which is taken into consideration when design of wireless transmission systems is done. Using of the channel impulse response (CIR) for this purpose is commonly applicable technique. The article presents methodology of obtaining CIRs on a way of numerical calculation for optical wireless transmission systems working indoor, including also those which work in scope of visible spectrum of light (VLC), based on the Modified Monte Carlo ray tracing method (MMC), which allows to determine the CIRs with really good quality for any room conditions in very short time.
