这项工作提出了一种用于蜂窝系统的大规模多用户MIMO (MU-MIMO)探测器,可以支持256个基站(BS)天线和32个用户,调制频率高达256- qam。该芯片的吞吐量为1.96 Gb/s,在290 MHz时功耗为87 mW。与最先进的探测器相比,该芯片的面积效率提高了5.7至30.5倍,归一化能量降低了9.2至31.2倍。
This work presents a massive multi-user MIMO (MU-MIMO) detector for cellular systems that can support 256 base station (BS) antennas and 32 users with modulation of up to 256-QAM. The chip delivers a throughput of 1.96 Gb/s and dissipates 87 mW at 290 MHz. Compared to the state-of-the-art detectors, the chip achieves a 5.7-to-30.5× higher area efficiency with 9.2-to-31.2× lower normalized energy.
