Base Station MIMO Detector Algorithm Implementations

In this paper, we implement a high throughput multiple-input multiple-output (MIMO) detector for single-carrier frequency-division multiple access (SC-FDMA) base station. High-level Synthesis (HLS) tool is used for implementing the algorithm on Xilinx Virtex and Zynq FPGAs. First, we compare the throughput performance and power consumption results of the different implementations. Second, we evaluate the quality of the results by comparing the HLS results to handwritten register-transfer level (RTL) implementations. In conclusion, the HLS tools have evolved into applicable implementation tools. Furthermore, the possible slight losses in the performance or design complexity with the HLS design method could be counteracted by choosing a higher category FPGA.
