Abstract: An apparatus includes a processor, and a transceiver operatively coupled to the processor. The transceiver is configured to split a set of modulated data symbols, based on a phase change between N consecutive modulated data symbols, to produce Q sets of data symbols, and generate, based on the Q sets of data symbols, Q sets of DFT spread data symbols. The transceiver is further configured to frequency domain spectrum shaping (FDSS) filter each set of the Q sets of DFT spread data symbols, via a different FDSS filter, to produce Q sets of FDSS filtered data symbols, and combine the Q sets of FDSS filtered data symbols. The transceiver is further configured to perform an inverse fast Fourier transform (IFFT) operation on the combined Q sets of FDSS filtered data symbols to produce a FDSS discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) signal, and transmit the FDSS-DFT-s-OFDM signal.
