Optimal Design of Aperture Array Receivers for Indoor Multicell Visible Light Communication System
ing at addressing the intercell interference in an indoor visible light communication system, aperture array receivers are designed and optimized herein. The aperture array receivers comprise a bare central detector and various receiving elements and use avalanche photodiodes as detectors. In the optimization problem, the maximum signal-to-interference-and-noise ratio is assumed as the optimization objective, and the interference-to-signal ratio is constrained to zero. The optimal structure parameters of the aperture array receivers are obtained under two receiving modes at the center of the room and ergodic positions. The results show that compared with generalized angle diversity receivers and a single avalanche photodiode, the bit error rate of the proposed receivers is decreased by at least 10 dB and 14 dB, respectively, in the center of the room. Furthermore, the signal-to-interference-and-noise ratio of the proposed receivers is improved by 6 dB and 15 dB, respectively, in ergodic indoor positions.
