“…Many studies on calculating the channel impulse response due to the multipath of the optical signal consider surface reflection in the environment as Lambertian or Phong reflection models [ 54 ]. Channel impulse response is suitable to analyze MP effects in communications [ 55 , 56 , 57 , 58 ] and LPS based on PoA or ToA [ 35 , 36 , 59 , 60 ], but in LPS algorithms based on AoA additional information is required [ 46 ].…”

In this paper, we characterize and measure the effects of the errors introduced by the multipath when obtaining the position of an agent by means of Indoor Positioning Systems (IPS) based on optical signal. These effects are characterized in Local Positioning Systems (LPSs) based on two different techniques: the first one by determining the Angle of Arrival (AoA) of the infrared signal (IR) to the detector; and the second one by working with the measurement of the Phase shift of signal Arrival from the transmitter to a receiver (PoA). We present the obtained results and conclusions, which indicate that using Position Sensitive Devices (PSD) the multipath effects for AoA have little impact on the measurement, while for PoA the positioning errors are very significant, making the system useless in many cases.

Abstract-Nowadays, the short range infrared wireless communication has become the most popular technique in In building communication. This paper has been described the modeling of wireless infrared channel by using time domain approach. Impulse response is the most imperative and critical parameter in IR wireless channel modeling. The Non-directed, Non-LOS IR (Diffuse) link configuration is taken into account for the simulation study. Our major attention is to obtain the received signal strength by moving the receiver at different locations in the entire rectangular room and suggest the specific area giving the maximum strength of the received signal. In order to perform this task of receiver location variability, the simulation analysis is carried out with the help of the three dimensional (3-D) plot.
