Abstract:
1. A method for implementation by one or more data processors forming part of at least one computing system comprising: receiving, by at least one data processor, data 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; determining, using at least one data processor, a final estimate of the multiple transmission signals 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 symbols of the first signal corresponding to the selected estimated multiple transmission signals; and providing, using at least one data processor, data characterizing the final estimate of the multiple transmission signals, the final estimate comprising the selected estimated multiple transmission signals that are selected at a plurality of iterations.
