In this paper a new simulation framework, based on Monte Carlo analysis, is proposed to allow performance studies of OOK and L-PPM in the wireless indoor infrared channel. It is assumed that the impulse response of the channel is known and that it is obtained previously by simulation using a ray-tracing algorithm. In the case of OOK, along with the Monte Carlo simulation structure, an analytic expression is developed additionally to provide direct performance evaluation of OOK in the wireless channel, which takes into account the effects of noise and inter symbol interference induced by multipath propagation, proper phenomena of this kind of communication channels. The simulation results obtained with the proposed simulation structures for OOK and LPPM are validated in both cases by comparison against theoretical results given by the evaluation of the expressions for probability of error in the AWGN ideal channel, free of inter symbol interference.
