A Robust Receiver for Generalized Spatial Modulation under Channel Information Errors Lee, JaeSeong; Woo, DaeWi; Jeon, EunTak; Yoon, SungMin; Lee, Kyungchun;
In this paper, we develop an iterative maximum likelihood (ML) receiver for generalized spatial modulation systems. In the proposed ML receiver, to mitigate the deleterious effect of channel information errors on symbol detection, the instantaneous covariance matrix of effective noise is estimated, which is then used to obtain improved ML solutions. The estimated covariance matrix is updated through multiple iterations to enhance the estimation accuracy. The simulation results show that the proposed ML receiver outperforms the conventional ML detection scheme, which does not take the effect of channel information errors into account.
