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

Downlink Multiple Input Multiple Output Mixed Sparse Code Multiple Access for 5G System
IEEE Access, 2018 For downlink multiple-input multiple-output-sparse code multiple access (MIMO-SCMA) system, the convergence reliability of the detected codeword in each decision process is unsatisfactory at the message passing algorithm receiver. To address this problem,

Extreme inputs/outputs for multiple input multiple output linear systems. [PDF]
, 2005 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 auto spectral densities of the inputs are specified, the phase relationships between the inputs are derived that will minimize or maximize the trace of the auto spectral density matrix of the ...
