On the performance evaluation of MIMO-SCMA systems

Massive multiple-input multiple-output (MIMO) systems is an emerging technology that is paving its way into wireless communication systems. Massive MIMO consists of tens or hundreds of antennas, which will result in an increase in capacity, reliability and performance. However, massive MIMO is facing many obstacles in terms of complexity due to the large number of antennas. In this paper, sparse code multiple access (SCMA) is introduced in MIMO systems. The interests of MIMO- SCMA resides in the need of lower number of antennas while preserving the system capacity thanks to the overload in SCMA. In this paper the performance of this system is studied in terms of throughput and both coded and uncoded bit error rate (BER).
