Tensor-Based Information Monitoring Receiver in UAV-aided MIMO Communication Systems

In this letter, we consider an unmanned aerial vehicle (UAV)-aided information monitoring scheme in a multiple input multiple output (MIMO) communication system. According to the tensor structure of the communication links, an information monitoring receiver is proposed. The receiver is based on the generalized tensor contraction (GTC), which exploits a nested parallel factor (PARAFAC) model for the received signals, via an iterative least squares (LS) algorithm to jointly monitor the data symbols transmitted from the users via the base stations. Compared with some competing receivers, our simulation results demonstrate the superiority of the proposed GTC-LS receiver in terms of normalized mean square error and bit error rate.
