Modulation Schemes in Wireless Optical Communication Systems

This detailed program on modulation schemes in wireless optical communications thoroughly covers theoretical principles, practical applications, and performance analysis of various modulation techniques. The implementation includes key algorithms for modulation/demodulation processes such as OOK (On-Off Keying), PPM (Pulse Position Modulation), and DPIM (Digital Pulse Interval Modulation) with corresponding BER (Bit Error Rate) calculation modules. Furthermore, it presents the historical evolution of modulation techniques, current research focuses including adaptive modulation algorithms and MIMO-OFDM implementations, along with future development trends. The program spans from fundamental concepts like channel modeling and synchronization techniques to cutting-edge technologies such as spatial modulation and machine learning-based optimization approaches. For researchers and engineers working in optical communication fields, this serves as an invaluable reference containing MATLAB/Python-based simulation examples and comparative performance evaluations under different channel conditions.
