Trilinear Spreading Code Based on Tensor Decomposition for the UAVs Uplink
In this paper,we use the trilinear tensor (PARAFAC) decomposition to model the Umanned Aerial Vehicles(UAVs) uplink which consists of a multiple-input multiple-output(MIMO) space-time- frequency(STF) scheme,the core of the tensor called as trilinear spreading code is jointly multiplexing and spreading multiple data streams over space (transmit antennas), time(chips) and frequency (subcarriers), the composite spreading code is given by the outer product of space-, time- and frequency- domain codes.At the same time,we analyse composing requirement and maximum diversity gain of the trilinear code.At the receiver, the two-step Alternating Least Squares (ALS) algorithm combined with scaling ambiguity eliminating is used for blind detection relying on a tensor modeling of the received signal.
