Abstract
Various embodiments of a method of mitigating interference in an OFDMA cellular network and a user terminal incorporating various of the embodiments. In one embodiment, the method includes: (1) selecting at least one dominant interfering signal, (2) generating estimates of a desired signal and the at least one dominant interfering signal, (3) jointly deciding based on the estimates such that an energy of a residual error is reduced and (4) mitigating interference based on the estimates.
