Limited Feedback Precoding for Wireless MIMO Broadcast Channels

Recently, a number of techniques have been introduced to exploit multiuser diversity of a wireless multiple-input multiple-output (MIMO) broadcast channel (BC) that consists of a base station (BS) with t transmit antennas and K mobile stations (MS) with multiple antennas. However, prior works have ignored the rate overhead associated with feedback of MIMO BC channel state information (CSI), whi...

Symbol-Level Precoding Design for Max-Min SINR in Multiuser MISO Broadcast Channels

In this paper, we address the symbol level precoding (SLP) design problem under max-min SINR criterion in the downlink of multiuser multiple-input single-output (MISO) channels. First, we show that the distance preserving constructive interference regions (DPCIR) are always polyhedral angles (shifted pointed cones) for any given constellation point with unbounded decision region. Then we prove ...

A Downlink Max-SINR Precoding for Massive MIMO System

To acquire the maximal array gain and mitigate the impact of pilot contamination, the downlink precoding algorithm on Max-SINR criterion was investigated and improved for Massive MIMO system. The objective function assured to maximize the utilization rate of the transmission power under the condition that SINR is not lower than the desired threshold. The Lagrangian function was deduced accordin...

Even-Integer Interference Precoding for Broadcast Channels

In this paper, an improved precoding strategy for broadcast channels, i.e., the transmission from one central transmitter (e.g., base station) to a number of distributed receivers (e.g., mobile terminals), is presented. The new scheme is a generalization of Tomlinson-Harashima precoding applied to multiple-input/multiple-output (MIMO) channels and a translation of concepts from lattice-reductio...

High SNR Analysis for MIMO Broadcast Channels: Dirty Paper Coding vs. Linear Precoding

We study the MIMO broadcast channel and compare the achievable throughput for the optimal strategy of dirty paper coding to that achieved with sub-optimal and lower complexity linear precoding (e.g., zero-forcing and block diagonalization) transmission. Both strategies utilize all available spatial dimensions and therefore have the same multiplexing gain, but an absolute difference in terms of ...
