Abstract: Abstract:This study explores a multiple-input and multiple-output (MIMO) channel measurement that makes use of a multiple-input and single-output (MISO) antenna configuration for various antenna spacings for indoor line-of-sight (LOS) Elliptical scattering propagation. With a 5-element uniform linear array (ULA) transmitted antenna system, dynamic measurements using a single antenna receiver moving over a spatial distance of 5m (~=30λ) is considered via angular spreads of ±9.9∘and ±1.8∘ associated with measurement routes A and B, respectively. With this dynamic measurement approach, simplified MIMO channel matrices were derived instead of using the product of the symmetrical correlation matrices at the BS and MS (eg. Kronecker matrix). The cumulative distribution functions (CDF) of the delay spread and the fading envelope are investigated and the maximum-to-minimum eigenvalue ratio (MMEVR) is analyzed based on the channel covariance matrices corresponding to different antenna spacings. In all cases, an explicit discrimination at an antenna spacing d < =λ/2 is revealed, where the MMEVR value tends to be significantly large. The mean delay spread is grossly independent of the antenna spacing and angular spread. These analysis results satisfy most scenarios for MIMO channel properties.
