Orthogonal Modulation and Demodulation Simulation

In this documentation, I have implemented comprehensive MATLAB simulations for orthogonal modulation and demodulation of AM, DSB, SSB, ASK, FSK, and BPSK signals. The simulation framework includes BER calculations across different SNR conditions using statistical analysis methods and error detection algorithms. The implementation involves key MATLAB functions such as modulate/demodulate for signal processing, awgn for adding white Gaussian noise, and berawgn for theoretical BER calculations. The simulation architecture utilizes I/Q components for quadrature modulation, where separate in-phase and quadrature carriers are employed for efficient spectrum utilization. Through these simulation experiments, I have derived significant conclusions regarding the performance and reliability characteristics of these digital communication schemes. The results demonstrate comparative analysis of modulation techniques in terms of bandwidth efficiency, power consumption, and noise resilience. For future research, further exploration could focus on optimizing modulation schemes using advanced algorithms like maximum likelihood detection or implementing adaptive modulation techniques. More detailed performance evaluation in practical applications could include channel coding implementations, multi-path fading scenarios, and real-time hardware-in-the-loop testing.
