This paper presents a linear Minimum Mean Square Error (MMSE) MIMO Detector design for MIMO-OFDM
systems based on Application-Specific Instrument-set Processor (ASIP). As part of the IEEE 802.11ac-compliant PHY baseband transceiver, the proposed MIMO detector offers low latency, high throughput with efficient resource utilization. The design has been synthesized with TSMC 40 nm CMOS technology, the logic
gate count for each QRD engine is about 245 K gates. It is able to support 20/40/80MHz bandwidth and up to 4 spatial streams. Detection latency for 80 MHz VHT mode (234 data sub-carriers) is 750 ns.
