In this paper, we propose a limited feedback transmission based on precoding mechanism for multiple-input multiple-output (MIMO) systems, referred as to supermode transmission. With a fixed data-rate, it allows different degree-of-freedom (DoF) depending on the current channel state information (CSI) and different transmission scheme with the same DoF. Through numerical examples, we show that the pairwise error probability (PEP)-based criterion outperforms the conventional criterion based on minimum eigenvalue (ME) of the received signal matrices, and the supermode transmission improves performance over both multimode MIMO (MM-MIMO) and multimode space-time block coding (MM-STBC), in particular, at low SNR regime.
