Abstract

This paper presents the concept, design and analysis for a visible light communications receiver utilising the angular and spatial diversity in order to achieve full mobility and protection from signal blocking in a typical home/office environment. The proposed receiver uses seven sub-receivers, each dedicated to an independent viewing angle and direction. Employing selection combining, the receiver with the strongest signal is used for the communications channel. Full performance evaluation and numerical analysis of the proposed system have been performed in MATLAB and compared to that of a single receiver. The received power, impulse response, corresponding signal-to-noise ratios and root-mean-square delay spread are also investigated.
