摘要: In this paper, we propose a tridimensional tensor coding for multiple-input multiple-output (MIMO) communication systems. This allows spreading and multiplexing the transmitted symbols in both space time domains, owing use of two allocation matrices. Assuming flat Rayleigh fading channels, signals received by K receive antennas during P blocks, composed N symbol periods each, with J chips per symbol, forma fourth-order that satisfies new constrained model. A two-step alternating least squares (ALS) algorithm is proposed blindly jointly estimating channel symbols. The performance blind receiver evaluated means computer simulations.
