%X <span>Massive multiple input multiple output (MIMO) systems can increase capacity and reliability greatly. However,&nbsp;</span><span>extremely high hardware costs and computational complexity lead to the demand for reasonable antenna selection.&nbsp;</span><span>Aiming at the problem that the traditional antenna selection algorithm based on maximizing sum capacity has large&nbsp;</span><span>complexity and worse bit error rate (BER) performance, a two-step selection algorithm is proposed, which selects&nbsp;</span><span>a part of the antennas based on the norm-based antenna selection (NBS) firstly, and then selects the antenna based&nbsp;</span><span>on maximizing capacity via convex optimization. The simulation results show that the improved algorithm has better&nbsp;</span><span>BER performance than the traditional algorithms. At the same time, it reduces computational complexity greatly.</span><br>
