Research on Real-time Free-Space Optical Transmission Experiment Demonstration based on Delta-Sigma Modulation

To simplify the structure of real-time coherent Free-Space Optical (FSO) / wireless systems and reduce costs, this paper implements a low-cost FSO system based on bandpass Delta-Sigma Modulation (DSM) technology. A 256-ary Quadrature Amplitude Modulation (256-QAM) signal with a bandwidth of 400 MHz...
