Abstract

Abstract:

A new layer-based precoding scheme is presented in multi-cell Multiple-Input Multiple-Output (MIMO) systems. Based on the traditional precoding algorithm, a layered precoding method is adopted in the intra and inter-cell separately. By means of the game theory and the concept of signal leakage noise rate, a precoding weights selection criteria and methods in each layer are also proposed. The scheme can obtain an interference suppression effect for multi-users in the multi-cell system. Simulation results show that the proposed algorithm, with low computational complexity, provides improvement over existing schemes.

Key words: MIMO, multi-cell, precoding, interference suppression
