Simulation of Carrier-Based QPSK Signal Transmission over Rayleigh Channels
Simulation of carrier-based QPSK signals propagating through Rayleigh fading channels with implementation details
DSB-SC Amplitude Modulation and Demodulation Implementation with MATLAB Code
Implementation of Double-Sideband Suppressed-Carrier (DSB-SC) modulation and demodulation using MATLAB or similar software tools. The code generates and visualizes: (1) Original signal and its frequency spectrum; (2) Carrier signal waveform; (3) DSB-SC modulated signal and its spectrum; (4) Power spectral density of DSB-SC signal; (5) Coherently demodulated signal waveform. The implementation demonstrates key communication system concepts using signal processing functions like fft(), hilbert(), and modulation techniques.
