and discrete Fourier transform spread OFDM (DFT-S-OFDM) sacrifice the baud rate with either zero-padded subcarriers in the high-frequency region to mitigate the frequency fading, or with a large ...

For this network, orthogonal frequency division multiplexing (OFDM) is believed to be one of the promising candidate waveforms where its performance depends on the accuracy of estimated CSI ...
