%X <span>Accurate estimationand real-time compensation for phase offset and Doppler shift are essential for coherent multi-</span><span>input multi-output (MIMO) systems. Here, a spatial multiplexing MIMO scheme with non-coherent frequency-shift&nbsp;</span><span>keying (FSK) detection is proposed. It is immune to random phase interference and Doppler shift while increasing&nbsp;</span><span>capacity. It is valuable that the proposed spatial multiplexing MIMO based on energy detection (ED) is equivalent&nbsp;</span><span>to a linear system, and there is no mutual interference caused by the product of simultaneous signals in square-law&nbsp;</span><span>processing. The equivalent MIMO channel model is derived as a real matrix, which remains maximal multiplexing&nbsp;</span><span>capacity and reduces the channel estimation complexity. Simulation results show that the proposed scheme has&nbsp;</span><span>outstanding performance over Rician flat fading channel, and experimental system obtains four times the capacity&nbsp;</span><span>through 4 antennas on both transmitter and receiver.</span><br>
