1. A method of processing signals at a receiver, comprising:
receiving, from a first transmitter, a first orthogonal time frequency space (OTFS) signal transmission comprising a first data stream, wherein the first OTFS signal is generated using a first basis matrix;
receiving, from a second transmitter, a second orthogonal time frequency space (OTFS) signal transmission comprising a second data stream, wherein the second OTFS signal is generated using a second basis matrix;
generating a first one dimensional data stream by OTFS decoding the first OTFS signal transmission;
generating a second one dimensional data stream by OTFS decoding the second OTFS signal transmission;
recovering the first data stream by operating a first feed forward equalizer and a first feedback equalizer and a first slicer, wherein a first residual error signal at an output of the first slicer is used as an input to the first feed forward equalizer and the first feedback equalizer and wherein an input to the first slicer is obtained by differencing an output of the first feed forward equalizer and the first feedback equalizer; and
recovering the second data stream by operating a second feed forward equalizer and a second feedback equalizer and a second slicer; wherein a second residual error signal at an output of the second slicer is used as an input to the second feed forward equalizer and the second feedback equalizer and wherein an input to the second slicer is obtained by differencing an output of the second feed forward equalizer and the second feedback equalizer.
