Fig. 1From: Low-complexity deep unfolded neural network receiver for MIMO systems based on the probability data association detectorDeep unfolding architecture. It is based on an underlying algorithm with an input vector given by \({\mathbf {x}}\) and an output determined by \({\mathbf {y}}\). Each hidden layer unfolds the \(\ell\)th iteration of this algorithm and its inputāoutput relationship is expressed by (18), whereas the output layer is represented by (17)Back to article page
