Comparison of three non-imaging angle-diversityreceivers as input sensors of nodes for indoor infrared wireless sensor networks: theory and simulation

Abstract

In general, the use of angle-diversity receivers makes it possible to reduce the impact of ambient light noise, path loss and multipath distortion, in part by exploiting the fact that they often receive the desired signal from different directions. Angle-diversity detection can be performed using a composite receiver with multiple detector elements looking in different directions.
