Abstract
Data can be received characterizing a first signal received on a plurality of antennas and comprising multiple transmission signals transmitted simultaneously on at least a same resource element in an orthogonal frequency-division multiple access (OFDM) communications system. A final estimate of the multiple transmission signals can be determined from at least the received data by iteratively estimating multiple transmission signals from the first signal and feeding back selected estimated multiple transmission signals, which satisfy a criterion, to cancel components of the first signal. Data characterizing the estimated multiple transmission signals can be provided. Related apparatus, systems, techniques, and articles are also described.
