MATLAB Code Implementation for OFDM System Simulation

Generate 0-1 random sequence => Serial-to-parallel conversion => Constellation mapping => Conjugate operation with oversampling => IFFT transformation => Add cyclic prefix/suffix => Apply windowing function => Parallel-to-serial conversion => Multipath channel transmission => Add AWGN noise => Serial-to-parallel conversion => Remove cyclic prefix => FFT transformation => Downsampling => Demapping => Calculate BER performance
