Abstract

The impulse response of the wireless infrared communication channel determines performances of communication system, such as multipath penalty over the maximum baud rate and hidden-station situations. It is significant to correctly describe the impulse response of the working channel for design and performance evaluation of communication systems. In this paper, details of a simulation package that obtains impulse responses for arbitrary wireless infrared indoor channels are presented. Capability of estimating the effects of shapes of room or objects, surface reflection and transmission characteristics on impulse responses is the most important feature of this package. The common simulation models just consider empty cubic rectangular room, with surfaces assumed to be Lambertian reflection pattern. With several examples given in this paper, the conclusions can be drawn that the common simulations models are not adequate to describe the real complicated communication environment and not suitable to the requirement of accurate performance prediction for the communication systems. The results give a demonstration that the use of the common simulation models to approximate the real wireless channels can introduce several decibels in the evaluation of the path loss.
