Abstract
In this paper a modification to the traditional Ceiling bounce model is proposed for use with non-directed indoor optical wireless systems which takes into account the transceiver separation distances as well as their actual positions while computing the impulse response. This modification is done by combining the results of DC gain computation and the statistical model along with the traditional Ceiling bounce approach. We show that the results of the proposed modification agree better than the traditional Ceiling bounce model with the reported experimental results of Barry et al. (1993. IEEE Journal on Selected Areas in Communications, 11, 367–379). The modified Ceiling bounce model is used to study the effect of transceiver positions on the rms delay spread and channel impulse response.
