Statistical Characterization of Indoor MIMO Channel Properties at 5.8GHz in the Office Building

Abstract

A wideband 4×4 MIMO (multiple-input multiple-output) channel sounding system has been developed to measure 16 Tx-Rx pair channels simultaneously using PN (pseudo noise) correlation method. Measurement campaign in the medium size office building with the developed channel sounding system is reported. Measured results are analyzed to compute channel parameters such as rms delay spread, mean excess delay, and their statistics. MIMO system capacity is also analyzed from measured channel impulse responses. Statistics of computed channel parameters can be used to develop empirical wideband MIMO channel models.
