Center node: "a dnn architecture for the detection of generalized spatial modulation signals"
  Abstract: In this paper, we consider the problem of signal detection in generalized spatial modulation (GSM) and explore the utility of the deep neural networks (DNN) for the detection task. We propose a DNN architecture which uses small sub-DNNs to detect the active antennas and the constellation symbols transmitted by the active antennas. Under the assumption of i.i.d. additive white Gaussian noise (AWGN), the proposed DNN detector achieves a performance very close to that of maximum likelihood detector. We also analyze the performance of the proposed detector under two conditions of practical interest: $i)$ correlated noise across receive antennas (resulting from mutual coupling, matching networks) and $ii)$ noise distribution deviating from the standard AWGN model. The proposed DNN-based detector learns the deviations from the standard model and achieves superior performance compared to that of conventional maximum likelihood detector.
