Multiple transmit antennas for low PAPR spatial modulation in SC-FDMA: single vs. multiple streams
The main reason for the selection of single-carrier frequency division multiple access (SC-FDMA) modulation technique in mobile high data rate communications lays in its low value of peak-to-average power ratio (PAPR).

Forward jamming mitigation using partially occupied DDMA‐MIMO waveform
We propose a partially occupied Doppler division multiple access (DDMA) waveform that only occupies a subset of DDMA Doppler channels, leaving a blank area in the Doppler space. Target echoes and clutter are confined to the occupied Doppler channels, while saturated forward jamming generates additional spectral peaks in the unoccupied Doppler channels.
