Transmission Scheme for Massive MIMO Systems Using Nulling-Based Approach
In this paper, a new transmission scheme is proposed for massive multiple-input multiple-output (MIMO) systems which will improve the performance of future 5G systems in terms of data rate and spectral efficiency, while accommodating a large number of users. We discuss massive MIMO systems, in which...

| description | In this paper, a new transmission scheme is proposed for massive multiple-input multiple-output (MIMO) systems which will improve the performance of future 5G systems in terms of data rate and spectral efficiency, while accommodating a large number of users. We discuss massive MIMO systems, in which diversity gain is very high (of the order of 104 for a 100×100 system) and a high data rate can also be provided. We propose new transmission schemes with different data rates for a massive MIMO system in Rayleigh fading. Diversity-multiplexing trade-off curve shows that more diversity gain can be achieved by utilizing more number of transmission time slots. It is also shown by simulation and analysis that if the number of receive antennas is less than the number of transmit antennas, then the detection of symbols can be performed by increasing transmission time slots. The statistical properties of the instantaneous signal-to-noise ratio are characterized at the receiver by deriving closed-form expressions of the moment-generating function (MGF). An approximate expression of the symbol error rate (SER) of the proposed scheme-based system is obtained by using the MGF expression. It is shown in the paper that the SER performance of the proposed scheme can be improved either by increasing the transmission time slots or increasing the number of receive antennas. |
