Sparse ordered repeated group decision feedback interference cancellation

摘要

In an orthogonal frequency division multiple access (OFDM) communication system, data characterizing a first signal received by a plurality of antennas, wherein the data includes a plurality of transmission signals transmitted simultaneously on at least the same resource element can do. The final estimated values of the plurality of transmission signals are obtained by repeatedly estimating the plurality of transmission signals from the first signal and feeding back the selected and estimated plurality of transmission signals that satisfy a predetermined criterion. By canceling one signal component, it can be determined at least from the received data. Data characterizing the estimated plurality of transmitted signals can be provided. Related apparatus, systems, techniques, and articles are also described.
