| gptkbp:feature |
high spectral efficiency
resistant to interference enables high data rates requires synchronization robust against multipath fading sensitive to frequency offset sensitive to phase noise subcarriers are orthogonal uses Fast Fourier Transform uses Inverse Fast Fourier Transform uses cyclic prefix uses guard interval uses multiple subcarriers |
