For those working on "MATLAB-based OFDM system simulation," check out my comprehensive resource! This integrated code combines two source codes from our platform, achieving perfect OFDM system simulation under MATLAB 7.0. The simulation workflow includes: audio data acquisition -> serial-to-parallel conversion -> 16QAM mapping -> IFFT processing -> cyclic prefix addition -> parallel-to-serial conversion -> transmission through ideal/multipath channels -> [...] (FFT processing, etc.) -> transmission result comparison (spectrum diagrams before/after transmission, audible quality assessment through audio file comparison - identical quality under ideal channel conditions). Special thanks to the two contributors who provided the original codes. This implementation demonstrates key digital communication concepts including modulation techniques, Fourier transforms, and channel modeling.
