Fj. Lopezhernandez et al., MODIFIED MONTE-CARLO SCHEME FOR HIGH-EFFICIENCY SIMULATION OF THE IMPULSE-RESPONSE ON DIFFUSE IR WIRELESS INDOOR CHANNELS, Electronics Letters, 34(19), 1998, pp. 1819-1820
A modified Monte Carlo method to calculate multipath dispersion due to
wall reflections on indoor wireless diffuse optical channels is prese
nted, As with other Monte Carlo methods, it allows evaluation of not o
nly the Lambertian but also specular reflections and can be used to va
lidate previous simulation schemes. The main difference is that for ea
ch ray traced and for each rebound, a contribution to the receiver is
calculated. This leads to a faster and more accurate simulation.
