Abstract

In this paper, we provide an analysis of an adequate dimension of multiple-input multiple-output (MIMO) system for full multiplexing in 16-QAM signaling. There are many results of small MIMO system with various schemes. However, because of the unrealistic complexity and meaningless required signal to noise ratio (SNR), results for large (over 20 data streams) MIMO systems can be hardly found. We obtain from our simulations the most efficient size of the MIMO system in a realistic SNR range for each given number of data streams. We also provide the computational complexity of each algorithm for MIMO systems with 20 or more data streams. We conclude from our simulations that the performance depends on the ratio of the number of receivers and the number of transmitters.
