Multiple-Input Multiple-Output (MIMO) Linear Systems Extreme Inputs/Outputs [PDF]
Shock and Vibration, 2007 A linear structure is excited at multiple points with a stationary normal random process. The response of the structure is measured at multiple outputs. If the autospectral densities of the inputs are specified, the phase relationships between the inputs

Measurement of keyhole effect in a wireless multiple-input multiple-output (MIMO) channel
IEEE Communications Letters, 2003 It has been predicted theoretically that for some environments, the capacity of wireless multiple-input multiple-output systems can become very low even for uncorrelated signals; this effect has been termed "keyhole" or "pinhole." In this letter, we present the (to our knowledge) first measurement of this effect.

Adaptive equalization of multiple-input multiple-output (MIMO) channels [PDF]
2000 IEEE International Conference on Communications. ICC 2000. Global Convergence Through Communications. Conference Record, 2002 The paper proposes and investigates a new approach to adaptive spatio-temporal equalization for MIMO (multiple-input multiple-output) channels. A system with n transmit and m (m/spl ges/n) receiver antennas is assumed. A decision feedback equalizer is considered.

The Effect of Spatial Multiplexing of the Interference on MIMO Communication Performance
IEEE Access, 2020 This work sheds light on the effects of spatially multiplexed interference on multiple-input-multiple-output (MIMO) networks. In particular, any increase in the number of interfering data streams (while keeping the total interference power constant) is ...
