SPAWC 2006, 7th IEEE International Workshop on Signal Processing Advances for Wireless Communications, July 2-5, 2006, Cannes, France
In this paper a deterministic PARAllel FACtor (PARAFAC) receiver is proposed, for Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems. We show that the received signal forms a 4-way tensor whose dimensions are space, time, and frequency, and can be written as a sum of tensor products (over paths and users) of four tensors representing the channel (for two of them), the symbols, and the modulation. Parameters of this model are identified via an Alternating Least Squares (ALS) algorithm, called DEBRE, whose identifiability conditions are pointed out.
