TL;DR: An 88 MIMOOFDM baseband transceiver compatible with the IEEE802.11ac specification is presented, and two 88 MMSE MIMO detectors based on Streassen’s matrix inversion have been designed for real-time MIMo detection.
Abstract: Multiple-input multiple-output orthogonal frequency multiplexing (MIMO-OFDM) is powerful in enhancing communication capacity or reliance. The IEEE802.11n standard defines use of four spatial streams in spatial division multiplexing (SDM). The task group of IEEE802.11ac will extend it to eight spatial streams. We present an 88 MIMOOFDM baseband transceiver compatible with the IEEE802.11ac specification. Two 88 MMSE MIMO detectors based on Streassen’s matrix inversion have been designed for real-time MIMO detection. To demonstrate MIMO-OFDM transmission, we have prototyped a FPGA-based testbed in 22 MIMOOFDM for field experiment and video transmission.
