Abstract
In this paper, we propose a tridimensional tensor coding for multiple-inputmultiple-output (MIMO) communication systems. This coding allows spreading and multiplexing the transmitted symbols in both space and time domains, owing the use of two allocation matrices. Assuming flat Rayleigh fading channels, the signals received by K receive antennas during P time blocks, composed of N symbol periods each, with J chips per symbol, forma fourth-order tensor that satisfies a new constrained tensor model. A two-step alternating least squares (ALS) algorithm is proposed for blindly and jointly estimating the channel and the transmitted symbols. The performance of the proposed blind receiver is evaluated by means of computer simulations. © EURASIP, 2011.101105De Almeida, A.L.F., Favier, G., Mota, J.C.M., A constrained factor decomposition with application to mimo antenna systems (2008) IEEE Transactions on Signal Processing, 56 (6), pp. 2429-2442De Almeida, A.L.F., Favier, G., Mota, J.C.M., Constrained tensor modeling approach to blind multipleantenna cdma schemes (2008) IEEE Transactions on Signal Processing, 56 (6), pp. 2417-2428De Almeida, A.L.F., Favier, G., Mota, J.C.M., Multiuser mimo system using block space-time spreading and tensor modeling (2008) Signal Processing, 88 (10), pp. 2388-2402De Almeida, A.L.F., Favier, G., Mota, J.C.M., Space-time spreading-multiplexing for mimo wireless communication systems using the paratuck-2 tensor model (2009) Signal Processing, 89 (11), pp. 2103-2116De Baynast, A., De Lathauwer, L., Aazhang, B., Blind parafac receivers for multiple access-multiple antenna systems (2003) Proc.
