Task-specific MIMO receiver system diagram
Supported by simulations, the system effectively suppresses spatial interference and recovers target signals in congested bands. A task-specific MIMO receiver (TSMRx) was implemented in 65 nm CMOS with beamforming, 2-bit ADCs, 4-point vector modulators, and a 25% sparse combiner, achieving task recovery while consuming just 75–115 mW over 0.5–3 GHz—setting a power efficiency record for this technology node.
