Abstract

There is provided a SIM-enabled transmitter (2) comprising a base station (2), Stacked Intelligent Metasurfaces, SIM (25) and a controller for jointly control the phase shifts of the electromagnetic waves passing through the meta-atoms of the SIM layers and the power allocated to each user equipment, using an unsupervised online dual-task deep-learning neural network (6). In response to the determination of an online channel estimation by the neural network, the transmitter implements iterations, each iteration comprising a forward propagation pass (504), a determination of a loss function (505), and a backpropagation pass (506). In the forward propagation pass (504), the online input data received by the neural network is passed through the successive hidden layers (601) of the neural network (6) using the current weights of the neural network (6), until arriving to a dual-task output layer that determines in parallel a predicted phase shift vector and a predicted power allocation vector, using the output of the last hidden layer.
