<p>This paper presents a user throughput performance analysis of a coordinated radio-resource scheduler with a hardware accelerator for the fifth generation of mobile communications systems (5G). To ensure fairness among mobile terminals (MTs) in 5G ultra-high-density distributed antenna systems, the transmission weight matrixes for a huge number of possible combinations of antennas and MTs have to be computed in a coordinated radio-resource scheduling process. To accelerate the computation, we devised a scheduler that executes the computation on dedicated hardware. System-level simulations reveal that the scheduler with a hardware accelerator composed of 5.3 Mgates obtains around 20 Mbps at the 5th percentile of average user throughput for 256 MTs. Computational resources are hence the critical factor in obtaining high average user throughput and ensuring fairness among MTs.</p>
