Numerical and experimental analysis of visible light communication (VLC) systems based on orthogonal chirp division multiplexing (OCDM) and orthogonal frequency division multiplexing (OFDM) are ...

OFDM spectrum efficiency is a key factor in wireless communications systems, as it determines how much data can be transmitted over a given bandwidth. However, OFDM also faces some challenges ...

the real and imaginary parts of the ofdm spectrum, the cross-correction value @nIFFT, the sum of the squares of the imaginary part of the pilots, and compares output bytes to input bytes. QAM ...

To recover the information signal, the output electrical signal is demodulated using a QAM demodulator, followed by an OFDM demodulator, and a QAM decoder. FIGURE 4. log(BER) vs. range under different ...
