Abstract

In optical wireless communication channel characterization, Monte Carlo-based non-deterministic modeling scheme has been widely adopted due to its simplicity and efficiency. Currently, this scheme is only applicable to characterize the optical sources with Lambertain radiation pattern. For flexibly modeling practical non-Lambertain source radiation patterns, the modified edition of above stochastic modeling scheme is systematically proposed in this paper. Numerical results prove that the modified scheme is capable of presenting various non-Lambertain sources with symmetric radiation pattern (e.g. LEDs LUXEON®Rebel from Lumileds Philips) at high accuracy while at significantly reduced computational complexity. As compared with the existing deterministic modeling scheme, the power deviation ratio of impulse response is less than 0.60% for the second order reflection while less than 13.8% for the third order reflection
