Performance analysis for 180° receiver in visible light communications

The paper presents the concept, design and analysis for a visible light communications receiver which has a full 180° perception angle thus offering the guard against blocking and enhancing the system mobility. The proposed receiver includes seven sub-receivers with the proposed geometrical shape investigated and analyzed in MATLAB

for evaluating the received power, RMS delay spread and corresponding signal to noise ratio. The results show that the receiver is fully mobile within the test area and can handle data rates far greater than that offered by commercially available LEDs for BER ≥ 10
