1. A user equipment (UE) for wireless communication, the UE comprising:
a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured to cause the UE to:
generate a pre-equalized discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) waveform associated with a multiple-input multiple-output (MIMO) communication system in accordance with applying a minimum mean square error (MMSE) pre-equalization to a DFT-S-OFDM waveform, the generation of the pre-equalized DFT-S-OFDM waveform including performing an inverse fast Fourier transform (IFFT) having a size that corresponds to a discrete Fourier transform (DFT) for processing the pre-equalized DFT-S-OFDM waveform at a receiver device; and
transmit, to the receiver device, the pre-equalized DFT-S-OFDM waveform.
