A Novel Transmitter Architecture for Spectrally-Precoded OFDM

Frequency nulling spectral precoding is an approach that suppresses the out-of-band emission in orthogonal frequency division (OFDM) systems. In this paper, we discuss the transmitter architecture of the spectrally precoded OFDM systems. We design a novel precoder that matches the practical implementation of the OFDM modulator. We show that spectral… CONTINUE READING
