Interference Management via Sliding-Window Coded Modulation for 5G Cellular Networks

Abstract

SWCM aims to mitigate the adverse effects of interference at the physical layer by tracking the optimal maximum likelihood decoding performance with low-complexity decoding and minimal coordination overhead. This article reviews the basic structure of the SWCM scheme built on the principles of network information theory, and discusses how it can be extended and implemented in practical wireless communication systems. Using a representative implementation based on LTE OFDM MIMO systems, extensive link-level and system-level performance simulations are carried out, which demonstrate that SWCM offers significant gains for all users over conventional interference-aware communication schemes. Network operating prerequisites for SWCM are also discussed to facilitate the standardization effort for its adoption in the fifth generation cellular network.
