This paper studies distributionally robust chance-constrained minimum variance beamforming. In contrast to deterministic modeling of the steering vector, our approach models the uncertainty statistically via distributions. We select the weights that minimize the combined output power subject to the distributionally robust chance constraint that for all distributions in the uncertainty set, the gain should exceed unity with high probability.
This paper investigates the optimal design of precoders or decoders
under a channel inversion criterion for multi-user (MU) MIMO filterbank
multicarrier (FBMC) modulations. The base station (BS)
is assumed to use a single tap precoding/decoding matrix at each
subcarrier in the downlink/uplink, resulting in a low complexity of
implementation. The expression of the asymptotic mean squared error
(MSE) for this precoding/decoding design in the case of strong
channel selectivity is recalled and simplified. Optimizing the MSE
This presentation introduces a Deep Learning model that performs classification of the Audio Scene in the subway environment. The final goal is to detect Screams and Shouts for surveillance purposes. The model is a combination of Deep Belief Network and Deep Neural Network, (generatively pre-trained within the DBN framework and fine-tuned discriminatively within the DNN framework), and is trained on a novel database of pseudo-real signals collected in the Paris metro.
