Precoding in Multiple-Antenna Broadcast Systems with a Probabilistic Viewpoint

In this paper, we investigate the minimum average transmit energy that can be obtained in multiple antenna broadcast systems with channel inversion technique.

Description
Summary:In this paper, we investigate the minimum average transmit energy that can be obtained in multiple antenna broadcast systems with channel inversion technique. The achievable gain can be significantly higher than the conventional gains that are mentioned in methods like (C.B. Peel et al., 2005). In order to obtain this gain, we introduce a selective mapping (SLM) technique (based on random coding arguments). We propose to implement the SLM method by using nested lattice codes in a trellis precoding framework.
