This paper presents concentrator and lens models for the detector and emitter, respectively, upon which a Monte Carlo ray‐tracing algorithm allows the evaluation of impulse response on infrared (IR) wireless indoor channels. We also present computer simulation results that show the effects of concentrator FOV and reception direction on the impulse response, received optical power, and channel rms delay spread, which allow us to propose structures for angle‐diversity receivers. © 2003 Wiley Periodicals, Inc.
