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
