A 1.96 Gb/s Massive MU-MIMO Detector for Next-Generation Cellular Systems

摘要

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.
