Generalized Space-Time Coded Massive MIMO System

摘要

This paper introduces a generalization of space-time block coding techniques for a massive multiple-input multiple output (MIMO) system. This generalized space-time coded massive (STCM) MIMO technique uses N_t number of transmit antenna arrays and N_r number of receive antennas. This allows the system to be more openly customizable to fit the needs of the wireless community and industry. With this generalization, the wireless system exploits the symbol diversity provided by the space-time coding and the interference cancelling abilities of the massive MIMO antenna arrays and linear pre-coding. This technique treats each massive MIMO transmit antenna array similarly to how a traditional space-time system would treat each antenna. Our results show that the proposed STCM-MIMO technique significantly outperforms traditional massive MIMO.
