摘要 提出通过优化发光二极管(LED)半功率角的布局来提高室内可见光通信系统性能的方法。4种典型的LED布局方式的仿真结果表明,该方法对于提高可见光通信系统的信噪比、降低信噪比的波动有明显效果。对于均匀的LED布局方式,信噪比的波动从未优化时的5.2 d B大幅下降到0.3 d B。该方法不需要调节LED的功率,更适合于工程运用。 This paper describes a method for optimizing the semi-angle at half power （SAHP） of a LED in order to improve indoor visible light communication. Four typical LED alignments are studied. The simulation results show that the proposed method increases SNR and reduces its fluctuation. Especial y in the case of evenly distributed LED alignment, SNR fluctuation reduces significantly—from 5.2 dB to 0.3 dB. A distinguishing feature of this method is that the same power is used for each LED, which makes this method feasible for practical applications.
