Abstract
Space-time coded massive (STCM) and space-frequency coded (SFC) massive multiple-input multiple-output (MIMO) wireless communication systems and methods of making and using the same are disclosed. The STCM-MIMO system utilizes two massive MIMO antenna arrays that transmit data over two or more channel vectors to a user with at least one receive antenna. This configuration permits the system to use the asymptotic orthogonal qualities of massive MIMO pre-coding to eliminate the interference from other users' channel vectors and signals. The system also maintains the diversity of space-time codes to recover lost data through treating each transmitting massive MIMO array similarly to a 2×1 Alamouti space-time code. The STCM-MIMO wireless system can significantly outperform those using space-time coding techniques only. The SFC massive MIMO wireless system may be similar to the STCM-MIMO wireless system, except for the encoder block. In the exemplary SFC massive MIMO architecture, instead of spreading the code across the time slots, the code is spread across the subcarriers.
