研究目的
Investigating the effects of a hybrid SCAP modulation format on visible light communication systems to improve throughput and reduce error vector magnitudes.
研究成果
The proposed hybrid SCAP modulation format improves the throughput of both m-SCAP and conventional m-CAP systems by up to 90% and 7%, respectively, with manageable error vector magnitudes. The format effectively combines the advantages of SCAP and m-CAP, offering a promising direction for future VLC system designs.
研究不足
The study is limited by the inherently lower modulation bandwidth of PLEDs and the trade-off between throughput improvements and bit error rate in the proposed hybrid modulation format.
1:Experimental Design and Method Selection:
The study proposes a hybrid SCAP modulation format combining SCAP and m-CAP for visible light communication systems.
2:Sample Selection and Data Sources:
Utilizes polymer light-emitting diodes (PLEDs) as transmitters in a VLC link.
3:List of Experimental Equipment and Materials:
Includes a Tektronix AWG70002A arbitrary waveform generator, Thorlabs PDA36A2 photodetector, and custom-built PLEDs.
4:Experimental Procedures and Operational Workflow:
Signals are generated, modulated, transmitted via PLEDs, received, and analyzed for error vector magnitude.
5:Data Analysis Methods:
MATLAB is used for signal processing, including resampling, filtering, and error vector magnitude calculation.
