Successive Interference Cancellation Implementation for ns-3 MU-MIMO mmWave Module

This paper presents a link abstraction model and ns-3 implementation of Successive Interference Cancellation (SIC) decoding for the uplink of a mmwave 5G network supporting Space Division Multiple Access (SDMA). The link abstraction model relies on the assumption that the physical layer (PHY) employs capacity-achieving channel coding on top of large Transport Blocks (TB) comprising a large number of OFDM subcarriers. This assumption is standard in the existing link performance models for 5G in ns-3. The proposed implementation is based on an openly available modified fork of the ns-3 mmwave module with support for Multi-User MIMO (MU-MIMO) SDMA. Simulation results validate the implementation and display PHY performance improvement due to SIC.
