Simulations of impulse response for diffuse indoor wireless channels [articol]

Abstract

Calculating channel impulse response is important in all forms of communications. In the case of diffuse infrared wireless networks channel response varies abruptly with changes in receiver/emitter position so the development of tools capable of estimating this response in any circumstances is even more important. Nowadays John Barry’s spatial discretisation algorithm is the most frequently used method of calculus [1]. In this paper we show a way to improve the algorithm’s speed and a way to account for the influence of both diffuse and specular radiation.
