Measurement of rotation effects in an indoor infrared channel

Abstract

In this paper, we report on a set of measurements performed at University of Ottawa to investigate the effects of rotation on the parameters of the indoor infrared channel model. The infrared channel is characterized by measuring the amplitude and phase response of its transfer function. The measurements have been performed in rooms with different shapes and physical properties. In each position, the receiver is rotated in steps of 5/spl deg/ and the channel transfer function is recorded in each step. Also, in each position, this set of results is collected for both diffuse and line-of-sight (LOS) configurations. Measurements are done in 9 rooms and a total of more than 5000 frequency responses have been collected. In this paper, we elaborate on the measurement set up, measurement procedures and present some of the results.
