摘要：
This paper presents the development of an 8-by-2 real-time multiuser-multiple input multiple output (MU-MIMO) testbed adopting Tomlinson-Harashima Precoding (THP) and limited channel state information (CSI) feedback. In this paper, we present an overview of the MU-MIMO testbed and show the implementation validity of the testbed. The experimental results show that the testbed achieves up to 2.4 dB degradation of BLER compared to the floating point computer simulation results.
