Semi-blind joint symbols and multipath parameters estimation of MIMO systems using KRST/MKRSM coding
In this paper, we propose a new MIMO communication system in a time-varying multi-path environment, using a Khatri-Rao space-time (KRST) coding combined with a multiple Khatri-Rao product of symbol matrices (MKRSM). It is shown the signals received at the receiver form a tensor which satisfies a (M + 2)-order nested PARAFAC model, where (M − 1)...
