Fig. 4From: Overlapping PPM for band-limited visible light communication and dimmingAchievable bit-rate versus perceived brightness level when N0 = 7.82 × 10-22 A2/Hz (r = 0.28 A/W, Ppk = 0.1 mW, BER = 10–6, B = 20 MHz). The superior performance of OPPM in this regime is evident. All schemes are band-limited across the entire dimming rangeBack to article page
