Average Power Reduction Techniques for Multiple-Subcarrier Intensity-Modulated Optical Signals
Abstract—We describe two classes of simple, effective techniques for reducing the average optical power requirement in intensity-modulated optical systems using multiple BPSK or ...

Average power reduction for MSM optical signals via sparsity and uncertainty principle
Multiple subcarrier modulation is an appealing scheme for high-data rate optical communication. However a major drawback is its low average power efficiency. While subcarrier res...

Power reduction techniques for multiple-subcarrier modulated diffuse wireless optical channels
In this paper, two novel techniques are proposed to reduce the average optical power in wireless optical multiplesubcarrier modulated (MSM) systems, namely in-band trellis coding a...
