The problem of separating superimposed digitally modulated signals using an array of antennas is considered. The proposed method exploits the finite alphabet structure to demodulate one signal at the time, resulting in a computationally efficient solution. The resulting signal estimates are shown to be exact in the noise-free case. In noisy scenarios, the performance is comparable with that of the iterative least squares approach, which demodulates all signals simultaneously at a higher computational cost.
