Optimization of Integer-Forcing Precoding for Multi-User MIMO Downlink

Multi-user Mimo Downlink Precoding for Time-variant Correlated Channels

Multi-user multiple-input multiple-output (MU-MIMO) systems provide a significantly increased capacity and spectral efficiency by exploiting the benefits of space division multiple access (SDMA). The channel state information (CSI) at the base station (BS) is used to precode the transmit signals and to simplify the processing at the users’ terminals. If perfect CSI is available at the transmitt...

Distributed Precoding with Weighted SLNR for Downlink Multi-user MIMO Systems ⋆

The use of precoding in the downlink of multi-user multiple-input multiple-output (MU-MIMO) systems can suppress co-channel interference effectively. Many schemes have been given to design precoding matrix for different optimization objective. In this paper, a distributed precoding scheme, named block diagonalization with weighted signal to leakage plus noise ratio (BD-WSLNR) for MU-MIMO system...

Precoding Schemes for MIMO Downlink Transmission

Hierarchical Precoding for the Network MIMO Downlink

Over the last few years, network MIMO or distributed MIMO has gained enormous interest in research and meanwhile is a candidate for future communication systems. However, existing techniques handling the multi-user interference, e.g., linear preequalization (LPE) or TomlinsonHarashima precoding (THP), assume full cooperation between the base stations. This might cause significant signaling over...

Novel Linear and Non-linear Multi-user Mimo Downlink Precoding with Improved Diversity and Capacity

Space division multiple access (SDMA) promises high gains in the system throughput of wireless multiple antenna systems. If SDMA is used on the downlink of a multi-user multiple-input multiple-output (MIMO) system, either long-term or shortterm channel state information has to be available at the base station (BS) to facilitate the joint precoding of the signals intended for the different users...
