The Effect of Spatial Multiplexing of the Interference on MIMO Communication Performance

open access: yesIEEE 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 ...

Block diagonalisation-based multiuser multiple input multiple output-aided downlink relaying [PDF]

open access: yes, 2012
A novel block diagonalisation (BD)-based Multiuser multiple input multiple output (MU-MIMO)-aided relaying scheme is proposed for downlink transmissions, which does not require any channel state information at the base station (BS) and decomposes a MU ...

Correlation characteristic analysis in diversity multiple‐input multiple‐output radar

open access: yesElectronics Letters, 2017
A huge limitation of the correlation analysis in existing scatterer model is that only uniformly distributed scatterers are considered ignoring the variability of scattering intensity in the real situation.
