A superposition modulation method, able to increase the peak data rate of intensity-modulation/direct-detection communication systems by the number of individually switchable light sources, is presented. This is possible by systematically delaying the binary-modulated light sources such that the sum signal is separable at the receiver. In this way the data rate can be increased by the number of available light sources.
